Abstract :
We evaluated characteristics of spatial filtering placed at the Fourier plane and signal processing about polytopic multiplexed recording method by using three dimensional analysis and Fresnel diffraction model. By using spatial filtering and signal processing, the signal-to- noise-ratio of reproduced image becomes to be improved.
