摘要
本文研究了基于计算机的光场分布的数值计算与显示方法。从光的菲涅尔衍射、波前相位重构入手,对连续信号进行了离散化处理,给出了数值计算公式。对光波通过矩形孔径、传播后的光场分布进行了数值计算与显示。仿真结果表明数值计算更加直观地展现了光的特性,并提供可视化的验证。
This paper investigates display and numerical computing method of optical fields distribution based on computer.The formula of numerical computing is presented with discretion for Fresnel diffraction.For example,light propagation through an aperture and numerical reconstruction result shows that exhibit obviously optical character with numerical computing,which provide visual validate for optics.
