摘要

为了在空间遥感详查相机研制工作中准确、有效地评价像移补偿系统的像移补偿效果

提出了采用分辨率为0.4μm的光栅尺作为像移补偿片台直线位移的检测元件

采用微机实现直线位移自动测量的检测方法并给出了详细设计思路

包括系统的硬件设计和软件设计。系统具有手动采样、定时采样、外同步采样等多种位移数据读取方式

并可以实时计算出像移补偿片台的位移、速度和速度误差。在实际工程检测应用中实现了极限误差优于0.5μm的检测精度。

Abstract

The method of how to use computer parallel interface and interrupt technology to design automatic measuring system of linear displacement is introduced in detail by using a grating meter with the resolution power of 0.4μm and the designs of hardware and software. The system can read the output data of grating meter by three methods: out trigger reading

inner timer trigger reading and manual reading. The maximum displacement measuring error of this system is 0.5μm.
