| Abstract: | In order to evaluate the comprehensive property of low light level (LLL) camera, the study on test resolution characteristic of LLL camera is carried out. In this paper,the system of testing the resolution characteristic of LLL camera is improved. The system is made up of neutral variabIe LLL lighting system. Optics foragery system,LLL camera,monitor and illumination meter. The principle and method of testing the resolution characteristic of LLL camera are stated. The resolution is the limit solving power in certain condition,that is space frequency of the thinest stripe resolved by LLL camera in the optimum condition. The test results are given in this paper. |
