What is image contrast of image intensifier camera

One of the technical parameters of the image intensifier camera is the image contrast of the image intensifier camera. What is the image contrast of image intensifier camera? Let’s take a look at it.

The image contrast of the image intensifier camera is to place a circular X-ray shielding lead plate equal to 10% of the effective area of the image intensifier camera at the center of the image intensifier. The ratio of the maximum brightness of the part without lead plate to the brightness of the part covered by the line plate is observed from the output screen, which is called image contrast.
Therefore, the bigger the image contrast of the image intensifier camera, the better the image contrast, the better the image effect of the image intensifier, and the quality of the image intensifier camera can be guaranteed. At present, the image contrast of image intensifier is generally 6:1, 12:1, 15:1 or higher.
The brand of image intensifier camera includes Newheek, Thales, Toshiba and so on.
