大口径望远镜 波像差检测 Shack-Hartmann传感器 Large aperture telescope Wavefront error test Shack-Hartmann wavefront sensor
摘要
为在外场环境下对大口径望远镜进行系统波像差的检验，研制了一套具有高探测能力的Shack-Hartmann波前传感器.利用恒星作为光源，对口径1 m、焦距11 m的大口径望远镜进行了波像差检验实验，测量结果为系统波像差在0.39λ~ 0.46λ RMS之间，且随着俯仰角的增加而增大，主要像差形式为3阶0°像散，与星点检验的结果一致.
Abstract
For testing the wavefront error of large aperture telescope in the outfield, a Shack-Hartmann wavefront sensor with high detect ability was developed. Using star as light source, the wavefront error of the telescope with 1 m diameter and 11 m focal length was test through the sensor. The results show that the wavefront error of the telescope is about 0.39λ~ 0.46λRMS, and the error increases as the elevation angle of the telescope. The dominating aberration is 3rd 0°astigmatism, and the result is identical to that of star test.
