高速转镜相机中倾斜光束的成象

本文通过建立几何模型 ,讨论了高速转镜相机光束倾斜入口的成象原理。证实了倾斜光束入口在转镜旋转时成象点的扫描轨迹是在以入射点为顶点 ,以成象点和入射点的连线为母线扫出的正圆锥底面的平面内 ,从而把空间光学的复杂设计问题简化成平面上的设计。此原理已用于 PDF- 2 0 0型平面转镜等待式分幅相机的设计

The Imaging of Inclined Light Beam in High-Speed Rotating Mirror Camera

The imaging principle of the high speed rotating mirror camera is discussed in the paper through setting up the geometrical model.The result shows that the locus of the imaging point are located in a plane which is a cone bottom surface formed by the scanning light beam.In this way we can simplify the complex design problem of space optics into the plane optics.The design principle has been used in the design of Model PDF 200 waiting type rotating mirror high speed framing camera.
