Research of timing design and adjusting methods of EMCCD

摘要

With development of low light level detection technologies, imaging systems based on EMCCD are widely applied. Timing design of EMCCD is one of the key factors for the imaging systems' designs. Considering with the electronic characteristics of EMCCD, timing design of one EMCCD imaging system is studied in this paper. Based on several solutions of EMCCD timing designs, influences of EMCCD's timing digital signals to imaging analog signals were observed and a timing adjusting method was found out. Simulation and test results of the proposed prototype shows that a signal adjusting phase precision of one degree is achieved at room temperature, and optimization of the timing signals has been implemented thereby improving imaging quality of the EMCCD's imaging system.
