摘　　要：提出了一种用计算机计算矩孔菲涅耳衍射的方法,通过对菲涅耳衍射积分公式的转换,把矩孔菲涅耳衍射公式用菲涅耳积分来表示,结合MATLAB和MAPLE的优点,在MATLAB中调用MAPLE的积分指令来实现对矩孔菲涅耳衍射场的计算.并给出了计算结果和这种方法用于计算单缝和半平面屏的菲涅耳衍射.A computing method with computer for the Fresnel diffraction of rectangular aperture is proposed. By transforming the integral of the Fresnel diffraction, the formula of the Fresnel diffraction for rectangular aperture is expressed by the Fresnel integral. Combining the virtue of the MATLAB and MAPLE, we use MAPLE integral order in the MATLAB language to carry out the numerical computing of the Fresnel diffraction and present the result of the numerical computing. This method is applied to compute the Fresnel diffraction of the single slot and half plane.
