摘要
用球面波照明物体的自由空间菲涅耳衍射 ,实现分数 (p>1)级傅里叶逆变换 ,提供了分数傅里叶逆变换无透镜光学实现的模式及其参量选择的法则 ,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 supplies a non-lens optical realiz ation model of inverse Fourier transform in fractional order (p>1 ) to get its Fresnel diffraction of an object in free space by illum inating it with a spherical light wave.This method also supplies the laws for pa rameter sulection and has practical value to optical information treatment.The r esults of computer simulation revealed the reliability and feasibility of the th eory. -
