6) aperture diaphragm
孔径光阑
1.
Based on diffraction integral formula and selfreproducing principle,diffraction integral equation for transverse modes in a circular symmetric resonator with an aperture diaphragm was disintegrated to finitesum matrix equation,and field distributions of transverse modes in the resonator were calculated by solving matrix for eigenvalues and eigenvectors.
结果证明,孔径光阑的位置和尺寸直接影响激光输出模式和花样。
补充资料：孔径满开测光
孔径满开测光
exposure measurement at open aperture
在单镜头反光相机上，在镜头的光圈满开的情况下，与光圈环的刻度相应地进行测光，现有的ttl照相机。大多都能做到孔径满开测光。用其他厂家的镜头或不与自动管圈联动的镜头，无法进行孔径满开测光，只得用拍摄光圈测光。
