| 摘 要： | 对基于多重分数傅里叶变换(FrFT)的三维(3D)物场计算全息图进行光电再现实验研究.根据分数阶与衍射距离的关系,对不同物面分别设置不同的分数阶,分别计算得到各层物面在全息面的复振幅并进行叠加,对其进行编码分别得到分数傅里叶变换振幅型全息图和相息图.同时在计算3D物场的全息图时,在物波面加入不同的随机相位因子,得到3D...

| Abstract: | Optoelectronic reconstruction experiment is carried out for holographic display of three-dimensional (3D) scene based on multiple fractional Fourier transform (FrFT).By setting different fractional orders according to different diffraction distances,multiple fractional Fourier transform in each object plane is calculated and superposed to the whole complex amplitude.The amplitude-type and phase-type holograms are obtained by encoding the whole complex amplitude in hologram plane.In order to suppress the spe... |
