Automatic character reading using a holographic data processing technique.
One of the useful applications of holography is information conversion. This paper reports on a newly developed automatic character reading system using code-transform holograms for analog-digital (A-D) conversion. Unknown characters are recognized by converting spatial analog character information to spatial digital information. System parameters are sampled out, and important factors such as (1) discrimination, (2) storage capacity, and (3) reading speed, which determine the performance of this system, are discussed.
