Full-view holographic image recording method

The invention relates to a method for recording a holographic image, and more particularly to a method for recording a full-view holographic image.

At present, the new optical photography technology is used to record the captured image on the optical holographic film, which has the advantage of the conventional optical photography image, and can provide the viewer with the stereoscopic image and the three-dimensional feeling. The basic principle of the conventional holographic flm image production is as follows (refer to FIG. 1): First, using a image capturing device 111 such as a CCD camera, one of the rotating platforms 112 is rotated at a fixed speed. The image of the object 113 is transmitted to the display panel 125 via a connection. At the same time, the same dimming light emitted by a light emitting unit 121, for example, a laser, is transmitted to a first mirror 122, which reflects the same dimming light to a beam splitter 123, and the beam splitter 123 divides the same dimming light into an object light and a reference. Reference light. The object light is transmitted along the object optical path P1, and the object light is transmitted to the second mirror 124, which reflects the object light to a display panel 125, and the image captured by the image capturing device 111 is captured. Transmitted and delivered to holographic film 128. In addition, the reference light is transmitted along reference optical path P2 to a third mirror 126 that reflects the reference light onto holographic film 128. The object light and the reference light then optically interfere on the holographic film to form a plurality of bright and dark interference fringe images. After the exposure, the holographic film is washed to record the image of the object Composite photographic film. For this composite hologram, a three-dimensional image of the object can be visualized by projecting the reference light as a reconstructed light source thereon.

However, there are still disadvantages and limitations in the images captured and recorded in the above manner. In the above process, the image taken by the recorder is a fixed angle (for example, fixed to the X axis by a certain tilt angle). Rotate the image 360 degrees. Therefore, during image reconstruction, the viewer cannot see the image of the tilt angle of the X-axis, and the image of the tilt angle of the Y-axis and the image of the tilt angle of the Z-axis cannot be seen. Therefore, the holographic image captured and recorded in the above conventional manner is insufficient for the viewer to be stereoscopic, and is not a true three-dimensional image.

Therefore, there are still many shortcomings and shortcomings in the recording technology of optical holographic images, and there is a need for further improvement.

In order to solve the above-mentioned drawbacks and disadvantages of the prior art, the present invention provides a method for recording a full-view holographic image, so that the captured and recorded image is not only an image 360 degrees around the target object, but also the target object can be recorded. Images were taken at an angle relative to the X-axis, Y-axis, and Z-axis.

The invention provides a full-view holographic image recording method, which is implemented by a full-view holographic image capturing and recording device, which comprises: a holographic image capturing device and a holographic image recording device.

The second rotating device has a second motor that can drive the film holder to rotate with the X axis as a rotation axis, and can achieve an inclination angle with respect to the vertical direction. The third rotating device has a third motor that can drive the film holder to rotate with the Z axis as a rotation axis, and can achieve an inclination angle with respect to the Z axis direction. The film holder is made of metal or plastic, but the invention is not limited thereto.

The holographic film is disposed on a film holder and is firmly held by the film holder provided thereon. The film holder can be driven by the first, second, and third motors to rotate in the Y-axis, the X-axis, or the Z-axis, such that the holographic film disposed on the film holder not only records the target object rotation 360 An image of the degree, and an image having a desired X-axis tilt angle, a Y-axis tilt angle, or a Z-axis tilt angle with respect to each degree can be recorded.

The present invention provides a method for recording a full-view holographic image, comprising the steps of: photographing a target object placed on the rotating platform rotating at a fixed speed using the image capturing device, and connecting the captured image via a connection Transmitting to the display panel; using the illumination unit to emit the same dimming light to the first mirror; the first mirror receiving the same dimming light and reflecting it to the beam splitter, the beam splitter splitting the same dimming light into object light (object light) and reference light; the spectroscope transmits reference light along the reference light (second) optical path to the third mirror; the third mirror reflects the reference light to the entire film holder Like a film; the beam splitter transmits object light along the object light (first) optical path to the second mirror; the second mirror reflects object light to the display panel, transmits and transmits to the entire film holder Like the film; and because the film holder of the film holder is rotated relative to the X-axis, the Y-axis, or the Z-axis, such that the holographic film is held on the film holder Not only can the image of the object rotate 360 degrees, but also the image with X-axis inclination, Y-axis inclination, or Z-axis inclination with respect to each degree, so the reference light and the object light will interfere with each other when they arrive on the holographic film. A full-view holographic image having one of an X angle, a Y angle, and a Z angle is formed.

Since during the holographic image recording process, the film holder can be driven by the first, second, or third motor to rotate relative to the Y axis, the X axis, or the Z axis, so that the film holder is placed on the film holder The holographic film not only records an image rotated 360 degrees by the target object, but also records an image having a desired X-axis tilt angle, Y-axis tilt angle, or Z-axis tilt angle with respect to each degree. After the exposure, the holographic film is washed to record a composite full image of the image of the target object. For this composite hologram, the reference light can be projected onto the reconstructed light source to reveal a three-dimensional image of the object.
