A Real Time Method for Fourier Transform Holographic Information Storage.

Abstract

An experiment was designed as it was shown in fig.l. S is white light source and is recorded as O(x0,y0). LCLV is a light crystal light valve in mixed field effect. Lens L1 forms image I(x,y) on CdS membrane of a light conducting layer of light valve. When voltage on liquid crystal layer > threshold of liquid crystal, a voltage image can be formed on CdS and liquid crystal which corresponds to input light image. (KAR) p. 5
