Abstract

A Fourier transform holographic memory has been developed and used for generating and storing sixteen thousand Kanji characters. The memory consists of four groups of holograms of 63 pages, recording 64 Kanji characters in each page, and has a packing density of 1.34 × 10⁷ bits/cm². Digitized characters of sixteen sizes can be generated with natural letter faces and good image quality. This paper focuses on the recording and reconstruction of holographic Kanji memory using a pseudorandom diffuser and systematic solutions consistent with optical, mechanical, and digital systems.
