针对星载航天遥感CCD相机成像焦平面位置检测的需求,本文设计一种用于航天相机成像焦平面位置检测系统。此检焦系统选用单片机80C32E芯片为主控制器芯片,设计了相机焦平面驱动控制部分、与上位机通讯接口电路部分、检测系统电源电路变换及控制器外围电路;最后对检焦系统进行了试验测试,测试结果表明检焦控制系统性能稳定,满足检焦控制精度8μm技术指标要求。
In order to meet the demand of imaging focal plane position detection of spaceborne remote sensing CCD camera, this paper designs a focal plane position detection system for space camera imaging. This inspection system uses the microcontroller chip 80C32E as the main controller chip, designed the camera focal plane drive control part, and the host computer communication interface circuit part, the detection system power supply circuit transformation and the controller peripheral circuit; Finally, the focusing inspection system was tested Tests and test results show that the performance of the inspection control system is stable and it meets the technical requirements of the indexing control precision of 8μm.
