遥感仪器的技术指标在很大程度上受光学遥感器焦面组件光机设计方案的影响。通过在实际中的设计应用,提出一种面 向探测器属性的光机设计思路。该设计首先确定主要设计输入,并依此将探测器视为光学件、结构件、电子学 件或者热控件,设计次级光机结构模块来满足相关要求,然后在此基础上展开成整个焦面光机设计 方案。随后依据该思路,针对四种情况给出了实际样例并加以解析,指出四种方案的优缺点。该设计 思路使得设计流程清晰化,可以为其他光学遥感器的焦面设计提供参考。

The technical qualification of optical remote sensors is largely affected by the opto-mechanical design scheme of focal plane assembly in these apparatuses. After some practical applications, a sensor-property-oriented design method is proposed. Firstly, the main requirements are confirmed in this method. Then opto-mechanical substructure is designed to satisfy these requirements by treating the sensor as optical, mechanical, electronic or thermal device. The whole opto-mechanical design scheme of focal plane assembly is developed on the substructure. Four different practical examples of this method are presented and their merits and drawbacks are explained, corresponding to four sensors’ properties. This method is claimed to be a more clearly design process and can work as a reference for opto-mechanical design of focal plane in other optical remote sensors.
