Abstract

Image intensifier is a device to observe in night. To evaluate the quality of Image intensifier, there are two important data which are resolution and SNR. Analyzing the testing principles of resolution and SNR, a test to super second generation image intensifier is designed. Under the luminance of 1Lx,1×10-3Lx and 1×10-5Lx, test with the same resolution card. It was found that image quality of Image intensifier has the best quality when in luminance of background 1×10-1Lx to 1× 10-3Lx. When luminance of its background is above 1×10-1Lx the noise will be high, see fig.2. When luminance of its background is below1×10-3Lx the signal will be weak. It provides a testing foundation for evaluating the quality of an image intensifier.
