详细研究了波纹光栏（ｓｅｒｒａｔｅｄａｐｅｒｔｕｒｅ）的菲涅耳衍射特征，提出并论证了调幅型正弦波纹光栏能在较大的菲涅耳数范围内有效地抑制光束中央部分的衍射调制，并给出这类波纹光栏用于高功率激光系统的设计程序。
The Fresnel diffraction characteristics of the serrated aperture were studied in detail. It was also proposed and demonstrated that the amplitude modulation sinusoidal baffle can effectively suppress the diffraction modulation in the central part of the beam over a large Fresnel number, This type of corrugated diaphragm is used in the design of high-power laser systems.
