一种光机扫描机构的设计

Design Scheme for a Kind of Optical-mechanical Scanner

光机扫描机构是各种航天航空遥感扫描成像系统的重要组成部分,而扫描镜及转动轴系又是其关键因素。从实际工程应用出发,着重论述一种大尺寸扫描镜的制备工艺以及光机扫描机构转动轴系的设计及校核方案,提出了一种45°平面反射镜扫描机构的关键实现技术和解决方案,经检验该方案切实可行。

Optical-mechanical scanner is an essential part of various remote sensing scanning and imaging systems for aerospace. Moreover, scanning mirror and rotational axis are the critical factors of the scanner. From the point of view of application, the preparation procedures of a large size scanning mirror and the scheme of design and calibration for rotational axis systems in optical-mechanical scanner were discussed. A kind of key implementation technology and solution for scanners with 45° plane mirror is proposed. The scheme was proved feasible by inspection..
