Abstract


Space laser communications are wireless communication , the success of the APT system for the entire communication process plays a decisive role . In order to ensure safe and reliable communication , APT system of tracking real-time , has a very high accuracy requirements , selection of APT system photoelectric sensor challenge the APT field sensor most of the CCD image sensor , but recently few years , due to technological problems , several advantages of CMOS image sensors is gradually emerging , low-cost , high- sensitivity , high- resolution , high dynamic range , easier integration , so that in the future development , CMOS image The sensor will gradually replace the CCD image sensor . Of this thesis is as a starting point, the video tracker based CMOS image sensors used in APT system is designed and implemented . Taking into account the laser communication in the field of view of a simple dark background , the bright spot of light characteristics , the design uses only one FPGA as core processor for control image acquisition and processing software , demonstrated two sets of spot identification and centroid calculation program , and the strengths and weaknesses of the program are given . To verify the feasibility of the CMOS image sensor applications in the APT system . I believe in the maturity of the technology , the design will be widely used in the APT system .
