Optical image processing is done in real time at the speed of light. Image acquisition at video ... L Hendler,MPC Watts - US 被引量: 102发表: 1996年 Optical image encryption based on multichannel fractional Fourier transform and double random phase encoding technique The optical image ...
Fourier-transform spectral imaging near the image plane By use of a detector array in the image plane of a Fourier spectrometer, a massively parallel Fourier spectrometer array can be constructed. This array is expected to collect efficiently spectral images with high spatial and spectral res... ...
