光线衍射 meaning in English

ray-casting

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。
