In this specific embodiment, the light source is LED light source.The sample is uniformity transmission device.The sample
For optical glass or film.During damage check, two kinds of polarization structures are provided between first polarizer and the second polarization, respectively
For the first polarization structure and second of polarization structure, the first described polarization structure is the polarization direction of first polarizer
It is parallel with the polarization direction of second polarizer, second of polarization structure for first polarizer polarization direction with
The polarization direction of second polarizer is vertical.
A kind of detection process of transmission-type sample damage detection apparatus of the utility model is to assemble this according to described above
A kind of transmission-type sample damage detection apparatus of utility model, the first polarizer and the second polarizer are placed on by sample to be detected
Between, then perform following steps：
(1) the first polarizer and the second polarizer are adjusted, makes the polarization direction of the first polarizer and the second polarizer parallel；
Imaging len is adjusted, makes camera to sample blur-free imaging, collection image I1。
(2) the first polarizer and the second polarizer are adjusted, makes the polarization direction of the first polarizer and the second polarizer mutual
Vertically, imaging len is adjusted, makes camera to sample blur-free imaging, collection image I2。
(3) image I is calculated according to equation below：
(4) drawing image I, and display image I.Because the defects of various damages, bubble, can change the polarization of imaging
Characteristic, therefore can obtain in image I the clear display of defect, can be right it is determined that on the premise of imaging system magnifying power
The size of damage carries out quantitative analysis.
A kind of transmission-type sample damage detection apparatus of the utility model is by light source, scatter plate, two panels polarizer, imaging lens
Formed with camera, light source and scatter plate can produce uniform illumination, and its structure is very simple；Package unit can be single simultaneously
Solely use, can also be placed in the light paths such as microscope imaging and use, application is very convenient.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
