Research On The Space Laser Communication System For High-Speed Image Transmission

Space laser communications with outstanding advantages such as broadband, high-speed, anti-interception capability, anti-jamming capability and small-scale.It has been widely used in deep space, Interstellar,satellite to ground,air-to-air,air-to-ground communication.This article mainly study in the space laser communication system for high-speed image trans-mission.The paper presents the overall design of laser image trans mission.The system includes CCD digital camera,data acquisition,FPGA image processing,data interfaces and the level conversion,laser transmission and real-time image displayThesis discussed on CCD digital camera, data acquisition, serializer and deserializer modules,data interface technology in detail. Focus on the FPGA data storage and extraction, image denoising technique, timing generator and control technology, and finally produce a standard VGA synchronous clock with the D/A circuit to generate a three-way RGB component VGA video signal into the display.
