摘　　要：基于Ｚｅｒｎｉｋｅ的零级谱位相修正法能将单束激光以几乎是１００％的高效率转换成规则或不规则的振幅阵列，我们给出了位相和照明孔径空间压缩比之间的关系，并用一对位相板在实验上实现效率达８９％，３／４空间压缩比的３×３方形照明阵列。Based on the Zernike method of the zero order spectral phase modification a single expanded laser beam can be converted into arbitrary illuminated shape with theoretical 100% efficiency with a pair of specific binary phase gratings. We have obtained the relation among the phases and the phase modulated space factor of the aperture.Experimental demonstration of 3/4 space factor, 3×3 π phase modulatedsquare areas with 89% efficiency is given.
