摘要
本文介绍一种星载航天相机调焦控制系统设计与实现。设计选用80C32E单片机作为调焦控制器,软件编程产生相序脉冲,驱动步进电机带动相机CCD焦平面运动,从而实现闭环和开环两种调焦功能。测试结果表明调焦控制系统性能稳定可靠,满足调焦精度8μm技术指标要求。此调焦控制系统已经成功应用于在轨相机上。
In this paper a focusing system of spaceborne camera is introduced.Sequence pulses,produced by programming in 80C32E microprocessor,drive the stepper motor to realize focusing CCD plane.And both closed-loop control and open-loop control focusing is realized.The experimental result indicate that this focusing system is stable and the precision is less than 8μm,which meet the technical requirement.
