Abstract

We propose the approach to designing a holographic disk memory with high storage density and high recording-reading rates. The approach consists in the synthesis of 3D memory be overlapping 1D expanded partial hologram on a moving carrier and the use of collinear optical heterodyning for data readout. The general architecture of such a memory is presented. The experimental results on recording and reading of wideband rf signals in the acoustooptical scheme are demonstrated.
