The coma aberation and astigmation are rec t ified through carefully selecting the position of aperture stop and the paramete rs of the quadratic surface.
仔细选取系统光,选取二次曲面系数及二次曲面,可以校正系统参差及像散。

仔细选取系统光,选取二次曲面系数及二次曲面,可以校正系统参差及像散。
As a practical example, an astigmation corrected scanning flat holographio concave grating (SFHCG) is designed and some results of the numerical and optical experiments are given.
给出一消像散SFHCG设计例和用这块光栅所验结果。
