Design and Implementation of Multispectral TDICCD Aerospace Camera Fast-View Integrated Ground Detection System
Aiming at the product development of the multi-spectral Time Delay Integration Charge Coupled Devices(TDICCD)space camera,the design scheme of the fast vision integrated ground inspection system is proposed in this paper,and the design scheme is realized by relying on the project.The design includes host system construction,CXP(CoaXPress)high bandwidth data transmission acquisition card,measurement and control acquisition card,map acquisition and control host computer,photoelectric parameter testing,non-uniformity correction and refresh chip reinjection.The design adopts integrated design,all the hardware and software are integrated into the local inspection host system,easy to carry and use.In this paper,a modular design method is adopted and a general host interface is used to realize the cross-use of various acquisition cards between different host systems.The universal data transmission interface,RS-422 transmission interface,makes the acquisition card applicable not only to the interface protocol of this camera,but also to other cameras after modifying the Field Programmable Gate Array(FPGA)code.It is proved that the ground detection system can effectively complete the functional test and photoelectric parameter performance test of multi-spectral TDICCD space camera,which provides a strong guarantee for the smooth progress of the project.
