A method of optical image subtraction is proposed. It provides parallel and real-time
amplitude subtraction of two images by using holographic interference in photorefractive …

Simple methods for performing real-time first-order image differentiation and quasi-
differentiation, using degenerate four-wave mixing with photorefractive crystals, are …

Photorefractive materials have been assuming ever increasing prominence in the non-linear
optics field due to their unique capability for displaying strong non-linear effects at milliwatt …

A new method of one-way image transmission through a thick dynamic distorter without the
need for a reference beam or four-wave mixing is demonstrated. In this method there are …

A general theory of the resolution of arbitrary novelty filters, optical as well as electronic,
including the only existing theory as a special case, is presented. Resolution is calculated …

The spatial fidelity of amplified images in photorefractive materials due to spatial gain
variations with computation and experiment based on BaTiO 3 is investigated. The results …

In many sensor protection applications, it is useful to selectively attenuate a strong coherent
beam in the presence of a collinear, weak white light image. We call a device which can …
