The phenomenon that light deviates from the straight path while it goes through a barrier of limited size is called diffraction of light 光通过有限大小的障碍物时偏离直线路径的现象称为光的衍射。
Nature of light , geometrical optics , and gaussian approximation , wave optics , interference of light , coherence , polarization of light , diffraction of light 光的性质、波动光学、几何光学及高斯近似、光的干涉、相干性、光的偏振、光的绕射、一些重要的应用实例。
In the first part , we have studied the stimulated algorithm of the diffraction of light ; and , through direct integral , convolution , and fourier transform , we created the numerical algorithm of fresnel integral and additionally , these three methods have also been compared in this paper 首先研究光线衍射传播的模拟算法,分别利用直接积分法、卷积法和傅里叶变换法实现了菲涅耳积分的数值计算方法,同时比较了这三种方法的优劣。
