由于发光物点不在光学系统的光轴上,它所发出的光束与光轴有一倾斜角。该光束经透镜折射后,其子午细光束与弧矢细光束的汇聚点不在一个点上。即光束不能聚焦于一点,成像不清晰,故产生像散。
Starting from the propagation law of partially coherent light, the spectral shifts and spectral switches of GSM beams focused by an astigmatic aperture lens are studied.
从部分空间相干光的传输理论出发,对被光阑像散透镜聚焦GSM光束轴上的光谱变化和光谱开关作了研究。
