摘　　要：为了克服菲涅耳衍射积分计算的复杂性和因光波频率高而导致的采样点数目巨大两大难题,利用Hankel变换算法,将二维计算变换为一维计算,并利用球面波因子处理,在普通PC上实现了菲涅耳圆孔衍射的计算机模拟演示.For overcoming the complexity of the computation of Fresnel diffraction through a circular aperture and the numerous samples of light wave, the Hankel transformation algorithm,the conversion of 2-D to 1-D and the processing of the spherical wave factor are applied. The simulative demonstration's implement of Fresnel circular aperture diffraction on PC is presented.
