The phenomenon that light deviates from the straight path while it goes through a barrier of limited size is called diffraction of light 光通過(guò)有限大小的障礙物時(shí)偏離直線(xiàn)路徑的現(xiàn)象稱(chēng)為光的衍射。
Nature of light , geometrical optics , and gaussian approximation , wave optics , interference of light , coherence , polarization of light , diffraction of light 光的性質(zhì)、波動(dòng)光學(xué)、幾何光學(xué)及高斯近似、光的干涉、相干性、光的偏振、光的繞射、一些重要的應(yīng)用實(shí)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 首先研究光線(xiàn)衍射傳播的模擬算法,分別利用直接積分法、卷積法和傅里葉變換法實(shí)現(xiàn)了菲涅耳積分的數(shù)值計(jì)算方法,同時(shí)比較了這三種方法的優(yōu)劣。
