Abstract The EMCCD is a kind of new devices for image acquisition,which have more applications both in theory and practice ,and in recent years there has been much concern from scholars at home and abroad. EMCCD has great potential and broad application prospects in real-time fast dynamic detection, detection sensitivity of detecting a true single-photon events, military reconnaissance, astronomical observations and the biomedical field. In the past few years, a large number of scholars at home and abroad went into the field, and has made a lot of achievements. Because of being used in low-light condition, you need to stretch its gray level, histogram equalization processing to achieve better observation.
First of all, this paper introduces EMCCD structure and operating characteristics, and analyzes the use of optical lenses, EMCCD and FPGA to develop board video capture output, and on this basis, the design module stretching algorithms achieve real-time gray-scale image on the screen, and the use of Matlab software analysis before and after the sample image processing gray, gray stretch algorithm design.
