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双透镜模式 ,给出了其光学实现基本单元参量选择的判定法则。对光学信息处理具有实用价值。计算机模拟实验证明了结论的可靠与可行。
It provides a double-lens model of fr actional Fourier inverse transform under general conditions to compare the Fresn e l 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 phas e factor.This model gives out a determine law for selecting the parameters of th e basic optical realization unit.The results of computer simulation revealed the reliability and feasibility of the theory.
