全景式航空相机扫描反射镜及支撑结构设计
|
摘要
扫描反射镜是航空相机光路转折、像移补偿和自准直调焦的关键部件,扫描反射镜及其支撑结构的设计水平对航空相机的性能有重要影响。以某全景式航空相机为例,在总结了扫描反射镜尺寸、轻量化结构、柔性支撑结构的一般设计方法基础上,设计了三角形和四边形轻量化孔组合形式的扫描反射镜结构,并提出了一种背部三点柔性支撑结构形式,经验证可以满足设计指标中对反射镜面型精度的要求。
Scanning mirror is a key component of aerial camera to realize the function of turning the optical path,image motion compensation and autocollimation focusing. The designing level of scanning mirror and its supporting structure has important influence on the performance of aerial camera. Taking a panoramic aerial camera for example,on the basis of summarizing the general design method of the size of the scanning mirror、lightweight structure and flexible supporting structure.Then a scanning mirror structure combined triangular and quadrilateral lightweight hole and a flexure supporting structure of three-point backside were designed. The design could meet the requirement of the surface precision.
