Wide Spectrum Radiation Gain Image Intensifier And Visual Field Defect Testing Technology Research

Wide spectrum image intensifier radiation gain test and flaw of field of view examination system is used for image intensifier detection before finished product. Besides, the system is also used for surface detection of image intensifier material.This topic research content of the paper includes the wide spectrum image intensifier radiation gain test system and the field of view flaw examination system.The paper first introduces the working principle of image intensifier as well as the development direction. In view of the national military standard of visible light incident degree of illumination of LLL image intensifier, the paper proposes incident degree of illumination normal value of the ultraviolet wave band and elaborates the basic principle of goal extraction, gives the testing method of the ultraviolet image intensifier. Then according to the measuring demand of the flaw of field of view, the paper designes the algorithm of goal extraction and analyzes the serviceability of the algorithm..The paper describes the hardware module, including photosource system, path of rays system, examination system, image collecting system and computer processing system. Then the paper describes the software design module, realizes each software module to control the system actively, and designs a friendly graph user interface.The experiment has been done with the designed test system to examine whether the test system is serviceabily.Finally, the paper summarizes the work, analyzes the insufficiency in the work as well as the forecast which will work to later.
