扇形孔径的远场衍射和锯齿形光阑的消高频衍射

SECTOR-TYPE APERTURES′S FAR FIELD DIFFRACTION AND THE DIFFRACTION OF DENTATE APERTURES USED TO CUT THE HIGH FREQUENCY

采用了一种简单有效的方法 ,模拟了一些扇形和部分环形孔径的远场衍射分布 .并讨论了大形激光工程中 ,锯齿形空间滤波器的消高频衍射 .

A simple and effective method is given to successfully simulate some sector type and ring type aperture′s far field diffraction ,and the high frequency cut of the dentate diaphragm in large scale laser application is also discussed.
