摘要
介绍了一种简单的用于在外场检测空间光学系统的方法,其主要原理是通过内置点光源和外部的平面镜使系统自身产生平行光从而代替大口径平行光管。通过相位差异(PD)算法可以从点光源的图像中反演得出系统的波相差。讨论了该方法的限制。给出了仿真结果,证明了该方法的实用性。
We introduce a simple method primarily developed for the performance evaluation of assembled space telescope in the field. The main idea of this method is to obtain the large parallel light beam for testing with an internal point light source and a plane mirror instead of large collimator. The wavefront error of the system can be calculated with phase diversity algorithm according to two images of the internal point source. The residual error and limitations of this method are discussed. A simulation is given at last, which shows the utilization potentiality of this aooroach.
