Abstract


The image intensifier night vision products , the most important optoelectronic imaging devices in the world , it is widely used in various fields of night vision technology, optical radiation measurement devices such as camera . Phosphor screen is an important part of the image intensifier , this article is around shimmer like intensifier phosphor screen parameters test technology research , each chapter reads as follows: The first chapter reviews and summarizes the development and application of optical imaging technology and night vision technology on the meaning and content of the study . The second chapter describes the shimmer like enhancer principle , characteristics , types and performance parameters . Focuses on the phosphor screen parameters and test methods . Chapter of the overall structure of the phosphor screen parameter test system , the mechanical structure , electron gun power supply , electrical control subsystem conduct a comprehensive analysis of the development , and focus on development of electrical control subsystem . Details the electrical control subsystem D / A card with the high voltage power supply , the A / D - card and the signal processing module , the relay card with a vacuum system, a luminance meter , the luminous flux of the tester and communication card . Chapter complete hardware developed based on the completion of the preparation of the test software . VC Language dialog box to write a phosphor screen parameter test system interface . External control voltage of the D / A card programming , high pressure control of high voltage power supply . A / D card programmed collection of screen flow and converted to a digital signal incoming computer . Of relay card programming to achieve control of the vacuum system . Programming control of luminance meter to measure the brightness and incoming computer . Test system and database records inquiries , additions or deletions . Chapter V of the full text summary, and pointed out the need to be further work to be done .
