Description of the Invention: [Technical Field] The present invention relates to an imaging system for a microscope, and more particularly to a confocal imaging system of a confocal microscope. [Prior Art] Referring to Figure 1 'Confocal microscope is a microscope that can "stereoscopically image" the object to be tested. The so-called "confocal" refers to the position of the light source of the imaging system 1 to be tested. The distance of the measuring surface 200 is equal to the distance from the imaging attack 12 to the beam splitter 13 plus the distance from the beam splitter π to the to-be-shoulder 200 of the object to be tested 1 ,, plus the imaging system! The spatial filtering is performed by the pinhole 14, and stereoscopic imaging of the object to be tested 1 〇〇 can be performed. Referring to FIG. 2, the imaging system 2 of the confocal microscope is a design of a pinhole rotating multi-spot optical path, and includes a light source module 21, a placing table 22 for holding the object to be tested 100, and a light source module. a first lens group 23 between the group 21 and the placement table 22, an imaging device 24 that receives light reflected from the object 1 to be imaged, and an image forming device 24 disposed between the light source module 21 and the imaging device 24. The second lens group 25. The light source module 21 has a light source 211 that emits white light, a pinhole array 213 having a plurality of pinholes 212 for passing light, and a δ is placed on the illuminating light source 211 and the pinhole disk 213. a microlens array 215 having a plurality of microchannels 214 for transmitting light, and a beam splitter 216 disposed between the pinhole disk 213 and the micro disk 215 and capable of splitting light. The pinhole disk 213 and the micro disk 215 are rotatable relative to each other, so that the light emitted by the light source 211 is selectively passed through the micro 稜鏡 214 of the portion 1279580 of the micro disk 215, and the pinhole disk 213 A portion of the pinhole 212 corresponding to a portion of the micro-twist 214 of the micro-disk 215 is formed in a plurality of independent beams to travel in the direction of the placement table 22 on which the object to be tested 100 is placed. The first lens group 23 has at least one convex lens for focusing the passing light to a predetermined area of the surface of the object to be tested 100; the second lens group 25 has at least one convex lens for focusing the passing light to the imaging device 24; The imaging device 24 can receive light focused by the second lens group 25 to create an image. When the imaging system 2 of the confocal microscope actually creates a stereoscopic image of the object to be tested, the light source 211 of the light source module 21 emits white light, and the white light passes through the pinhole disk 213 and the micro disk 215 which are rotated relative to each other. Because it must pass through the corresponding pinhole 212 and the micro-inch 214 at the same time, it is selectively divided into a plurality of beams; the beams pass through the first lens group 23 and are respectively focused to a predetermined area of the object to be tested, and reflected. The trailing edge of the original light path passes through the pinhole 212 and passes through the beam splitter 216 in the light source module 21 to change the direction of travel to the direction of the first lens group 25, and is respectively focused after passing through the second lens group 25. To the imaging device 24, after the imaging device receives the reflected beam of each region of the object to be tested 100, an enlarged stereoscopic image of the whole @i(9) to be tested is established. The image forming system 2 of such a confocal microscope mainly uses the matching and combining of the pinhole disk 213 and the micro disk 215 which are rotated relative to each other in the light source module 21, and at the same time, multi-point imaging is performed, so Different artifacts _, or the resolution of the image to be created, must also match the pinhole disk 213 of different pinholes. The more complicated the appearance is, or the more the resolution is the same as the needle of the pinhole disk 213 The aperture of the aperture 212 must also be smaller; while at the same time 1279580, the intensity of the white light provided by the source 211 must also be correspondingly enhanced for the pinhole disk 213 of different pinhole apertures to provide light sufficient to reflect the focused light intensity for the imaging device 24 Receive and create images. Therefore, the imaging system 2 of such a confocal microscope has practical use, and has to replace the pinhole disk 213 and the light source 211 in the light source module 21 in response to different measurement conditions and required measurement results. Components, so the use of the measurement is less flexible, and must be prepared at a higher cost of purchase of various components, in order to meet the needs of different measurement needs to be improved 发明 [Summary] Therefore, the object of the present invention is A confocal microscopic imaging system is provided which is capable of measuring a variable-variable light source image that uses a large elasticity and can quickly establish a stereoscopic image of an object. Thus, the present invention provides a confocal microscopic imaging system with a variable source image comprising a light source module, a filtered polarization conversion device, an optical device, a piezoelectric platform, a + lens group, and a digital position. The light source module has a light source, a digital microlens through which the light emitted by the light source passes, and a control that can programmatically control the microlens to pass the light emitted by the light source into a predetermined pattern and travel in a first direction. The unit 〇 the filtering polarization conversion device causes the passing light to be a polarized light having a predetermined wavelength range that continues to be directed toward the first square, for the light of the predetermined pattern emitted from the light source module to pass through Traveling in one direction! 27958〇 first—polarized beam. Position change: the polarization beam splitting device makes the direction of the electric field vibration of the polarized light passing through and the opposite direction = and makes the polarized light with different directions of the electric field vibrate toward different directions, respectively, for the first polarized light beam to pass through and then continue to A second polarized beam that travels in a first direction. The hai piezoelectric platform is configured to receive and drive the displacement of the object to be tested. The lens-group is disposed on the polarizing beam splitting device and the piezoelectric platform and has at least a convex lens, and the second polarizing beam can be surfaced Focusing on the surface to be tested of the object to be tested, and when the second polarization 1 is fully focused to the surface to be measured, the second polarized beam is reflected by the surface to be measured into a third polarization The light beam is opposite to the first direction and passes through the polarization beam splitting device to form a fourth polarized light beam traveling in a second direction. The digital imaging device is configured to receive the fourth polarized light beam and receive the digitally polarized light beam in a digital manner. The fourth polarized light beam is established as an enlarged image of the surface to be tested of the object to be tested. [Embodiment] The foregoing and other technical contents, features and effects of the present invention are in conjunction with a preferred embodiment of the following reference drawings. In the detailed description, the present invention will be clearly described. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. A first embodiment of a confocal microscopic imaging system 3 for tunable variable source images includes a light source module Η, a wave polarization 8 1279580 conversion I set 32, a polarization splitting device 33, a piezoelectric platform 34, and a The first lens group 35 and the digital imaging device 36. The light source module 31 has a light source 311, a digital microlens 312 through which the light emitted by the light source 311 passes, and a programmable control of the microlens 312. The light emitted by the remote light source 311 passes through the control unit 313 which is in a predetermined pattern and is pushed in a first direction. The control unit 313 can establish the resolution of the image according to the appearance complexity of the object 1 实际 or the actual resolution required to establish the image. The light emitted by the control light source 311 passes through a light spot pattern having a smaller cross-sectional area and a denser arrangement as shown in FIG. 4, or a larger cross-sectional area and a denser arrangement as shown in FIG. The filter polarization conversion device 32 causes the passed light to be a polarized light having a predetermined wavelength range that continues to travel in the first direction, and has a light beam for sequentially traveling through the first direction. 3 21 (m (four) and - polarized light is converted to 322 (PS c〇nverter), the filter 321 can filter out stray light and only pass the light of the pre-twist wavelength, and the polarizing converter 322 will pass the filter 321 The light of the predetermined wavelength range is converted into p〇iarized light, and the light of the predetermined pattern emitted from the remote light source module 31 passes through the first polarized light beam which travels in the first direction. In the example, the multiplexer passes only green light having a wavelength of 550 nm, and the polarization converter 322 converts the green light into p-type line polarized light (p linear_p〇larized Hght) so that the first-polarized light beam is in a predetermined pattern. The p-type line polarized light having a wavelength of 55 〇 nm. The polarized light splitting device f 33 causes the direction of the electric field vibration of the polarized light passing through and the phase change ki to make the polarized light having different electric field vibration directions travel toward different directions of 9 1279580, respectively. There is a polarizing beam splitter 331 (polarization beam splitter) and a quarter wave plate 332 (λ/4 plate) for sequentially passing the polarized light traveling in the first direction, and the polarized light splitting isolator 331 is limited Electric field vibration directions are orthogonal to each other The two polarized lights respectively travel in a second direction that is different from the first direction in the first direction (here, the first and the two sides are perpendicular to each other as an example), and the quarter wave plate 332 will face The linearly polarized light traveling in the first direction is converted into a circular p〇iarized light that continues to travel in the first direction, and the circularly polarized light traveling in the opposite direction is converted into a continuous anti-reverse The line traveling toward the first direction is polarized, and the first polarized beam is passed through to form a second polarized beam (left-handed circularly polarized light) that continues to travel in the first direction. The piezoelectric platform 34 is used for receiving the object to be tested, and can drive the object to be tested 100 for three-degree spatial displacement in a nanometer step. The first lens group 35 is disposed between the polarization beam splitting device 33 and the piezoelectric platform 34, and has at least one convex lens, and the second polarized light beam can be globally focused to the object to be tested in the form of a surface. One of the surfaces to be tested is 2 〇〇. The one-child digital imaging device 36 includes a photo-coupled camera 361 (CCD camera) that can receive light and image, and an arithmetic unit 362 that can process the image formed by the photoelectric coupling camera 361 for receiving the first a fourth polarized light beam that is totally focused on the plane to be measured and that is reflected and travels in the second direction (related changes in the direction of travel, phase, direction of vibration of the electric field, etc.) And the received fourth polarized light beam is digitally established as an enlarged image of the to-be-measured surface 2〇〇 of the object to be tested. The confocal microscopic imaging system 3 of the adjustable variable light source image of the present invention is actually 10 1279580. When the stereoscopic image of the object to be tested 100 is established, the resolution of the enlarged image is first modified by the control unit 313 of the light source module 31. The image of the digital microlens 312 is such that the light emitted by the light source 311 passes through a predetermined pattern (the resolution is higher, the smaller the cross-sectional area of each beam, and the more dense the arrangement is), the first direction is performed. After the light passes through the filter 321 of the filter, wave polarization conversion device 32 and the polarization converter 322, the first polarized beam of the p-type line polarized light having a wavelength range of green light continues to travel in the first direction and passes through the polarization. When the polarization splitting isolator 331 of the spectroscopic device ,, since the first polarized beam is a 线-type line polarized light, it continues to travel in the first direction and passes through the quarter-wave plate 332, and passes through the quarter-wave #332. The second polarized light beam that is converted into a circularly polarized light (left-handed auroral light) continues to travel in the first direction. When the second polarized light beam continues to travel in the first direction and passes through the first lens group: 5, it is globally focused to one of the surfaces to be tested 1 ,, at which time the second polarized light beam is to be measured. The fine reflecting surface is reflected as a third, and the vibrating beam travels along the original optical path in the opposite direction - since the third polarized light beam is reflected by the second polarized light beam, the third polarized light beam is inverted from the second polarized light beam. Round biased aurora (right-handed aurora). When the third polarized light beam continues to pass through the quarter-wave plate 332 of the polarization splitting beam 33, the fourth polarized light beam converted into the s-shaped line polarized light by the quarter-wave plate continues to be reversed. The first direction travels and is restricted in switching while passing through the polarization splitting isolation 331 to travel in a second direction perpendicular to the first direction. When the fourth polarized light beam continues to travel in the second direction, it is received by the optical fiber camera 361 of the digital imaging 1279580 device 36, and the one to be tested surface 200 of the object to be tested (9) establishes an enlarged image. And then cooperate with the "platform 34 for perpendicular to the object to be tested! (9) The depth step of the one to be tested surface 200 can sequentially create an enlarged image of the different to-be-measured surfaces of the plurality of objects to be tested (10), and then the arithmetic unit 362 The magnified stereo image of the object to be tested can be obtained quickly and correctly. Referring to Figure 6, the second embodiment of the confocal microscopic imaging system 3 of the present invention is a similar to the confocal microscopic imaging system 3 described above. The difference is only in the polarization beam splitting device 33. Between the digital imaging device 36, a second lens group 37 having at least a convex lens is disposed to image the fourth polarized light beam emitted from the polarization beam splitting device 33 in the form of a surface. The device's photo-electrical camera is received to create a sharper magnified image.
