摘要
用波前相因子判断法 ,将球面波照明物体的自由空间菲涅耳衍射光场分布与分数傅里叶逆变换的标准频谱分布进行位相比较 ,提供了广义条件下光学分数傅里叶逆变换的无透镜模式 ,给出了其光学实现基本单元参量选择的判定法则。计算机模拟实验证明了结论的可靠与可行。
It provides a non lens model of fractional Fourier inverse transform under general conditions to compars the Fresnel diffraction light field distribution of an object illuminated by a spherical light wave in a non free space with the justification method of wave front phase factor.This model gives out a determine law for selecting the parameters of the basic optical realization unit.The results of computer simulation revealed the reliability and feasibility of the theory.
