一种用于空间目标捕获的宽视场可见光光学系统的设计

设计了一种对空间目标进行捕获并跟踪的可见光相机的光学系统.该成像系统采用了7组共8片的复杂化双高斯结构,焦距40.65 mm,相对孔径为1/1.7,全视场角28°,光谱范围为可见光谱段.该系统可完成对空间目标的捕获和跟踪测量任务,并提供目标图像信息.针对大视场大相对孔径的空间目标探测要求提出了光学系统参量的确定方法,结合设计实例给出一种双高斯向反远距演变的设计思路.

Optical System Design of Visible-spectra Camera for Space-object Capture

An optical design of wide field camera used for space-object capturing was presented.The Double-Gauss Configuration was adopted in the lens system which has an effective focal length of 40.65mm,an F-number of F/1.7,a field of view of 28°,and it works in the range of visible spectrum.The camera was supposed to accomplish the tasks of objects capturing and tracing.The method to determine the optical system parameters to meet the need of wide field of view and large F-number was presented.The approach of an optical structure,which is a hybrid of Double-Gauss and Anti-telephoto,was given..
