The image acquisition units alignment methods that the application is provided, by using the fixed reflective microscope group and the camera lens it
Between distance, fine setting the distance between the photo-sensitive cell and the camera lens, to realize reflective mirror described in image acquisition units
Alignment between group, the camera lens and the photo-sensitive cell, effectively shortens the alignment time, substantially increases alignment efficiency, and
And can intuitively judge that the distance between the reflective microscope group, the camera lens and described photo-sensitive cell are according to imaging effect
No adjustment is suitable, so this method also substantially increases the imaging effect after alignment.
In the first embodiment of the image acquisition units alignment methods of specific the application as shown in Figure 6, described image is adopted
Collecting unit includes reflective microscope group, camera lens 13 and photo-sensitive cell 14；Methods described includes：
S101：Adjust and fix the reflective microscope group and the camera lens, the light for reflecting certificate to be identified passes through described
Reflective microscope group is reflected into the camera lens；
In specific implementation process, the reflective microscope group includes at least one piece reflective mirror.In view of the reflecting surface of reflective mirror
Diffuse reflection effect, it is preferable that the reflective microscope group only includes two pieces of reflective mirrors.Certainly, the reflective microscope group can also include
Three pieces of even more reflective mirrors, to reach that other are suitable to practical purpose, only need the light of certificate reflection to be identified to pass through institute
Stating can be imaged in the photo-sensitive cell 14 after the reflection of reflective microscope group.
So that the reflective microscope group only includes the embodiment of two pieces of reflective mirrors as an example, as shown in fig. 7, the reflective microscope group bag
The first reflective mirror 11 and the second reflective mirror 12 (can be referring to Fig. 1 to Fig. 3) are included, is adjusted and the fixed reflective microscope group and the camera lens
Comprise the following steps that：
S1011：First reflective mirror 11 is fixedly installed in the first reflective mirror fixed mount 21, by second reflective mirror
12 are fixedly installed in the second reflective mirror fixed mount 22, make the reflecting surface of second reflective mirror 12 parallel to first reflective mirror
11 reflecting surface；The light of certificate reflection to be identified is reflective into described second after the reflection of first reflective mirror 11
Mirror 12；
S1012：The camera lens 13 is fixedly installed in lens fixing bracket 23, and adjusts the camera lens 13, makes the camera lens
Angle between the reflecting surface of 13 optical axis direction and second reflective mirror 12 is 45 degree；The light of certificate to be identified reflection according to
After the secondary reflection by the reflection of first reflective mirror 11 with second reflective mirror 12, into the camera lens 13.
So far, step S101 is completed, after reflection of the light that certificate to be identified reflects by the reflective microscope group, can be entered
The camera lens 13.
S201：Position of the photo-sensitive cell 14 relative to the camera lens 13 is adjusted, makes the light through the camera lens 13
Into the photo-sensitive cell 14, and the image plane of the camera lens 13 is overlapped with the plane where the photo-sensitive cell 14.
Here, still so that reflective microscope group described above includes the first reflective mirror 11 and the second reflective mirror 12 as an example, adjusting institute
Position of the photo-sensitive cell 14 relative to the camera lens 13 is stated, is comprised the following steps that：
S2011：The photo-sensitive cell 14 is arranged on the photo-sensitive cell fixed mount 24, the photo-sensitive cell 14 is adjusted
Angle between the optical axis direction of the plane at place and the camera lens 13, makes to enter described photosensitive through the light of the camera lens 13
Element 14；Preferably：
S2011’：It is 90 to adjust the angle between the plane where the photo-sensitive cell and the optical axis direction of the camera lens
Degree.
S2012：Adjust the distance between the photo-sensitive cell 14 and described camera lens 13, make the image plane of the camera lens 13 with
Plane where the photo-sensitive cell 14 is overlapped, so that the photo-sensitive cell 14 being capable of blur-free imaging.Preferably：
S2012’：The photo-sensitive cell 14 is adjusted to move up perpendicular to the direction of the plane where the photo-sensitive cell 14
It is dynamic, until the image plane of the camera lens 13 is overlapped with the plane where the photo-sensitive cell 14.
The angle between the plane at the place of photo-sensitive cell 14 and the optical axis direction of the camera lens 13 is first adjusted, so
Element 14 is strolled described in movement again afterwards, the distance between the photo-sensitive cell 14 and described camera lens 13 is adjusted.
After being adjusted, the light of certificate reflection to be identified is set to be reflected into the camera lens by the reflective microscope group
13, and the photo-sensitive cell 14, and the image plane of the camera lens 13 and the photosensitive member can be entered after through the camera lens 13
Plane where part 14 is overlapped, you can is realized and clearly, is intactly imaged.
