Abstract

Noise property is one of the main properties of LLL CCD camera. It indicates the limited detection ability of LLL camera. At present test and analysis technique on noise of LLL camera plays a very important role in the area of night vision technology. In this paper, taking the LLL CCD camera, which our research laboratory developed as the object of study, a novel method, 3D test and analysis technique on time-space SNR of LLL camera, is put forward. By using image board as signal sampling device, through the close coordination of electronic computer and image board in hardware linkage and software programming, the LLL camera 3D SNR test and analysis system is set up. Using this system, the 3D time-space SNR of the LLL CCD camera, which our research laboratory developed is tested and analyzed successfully.
