Photorefractive deconvolution techniques for optical differentiation of images

JA Khoury, RW Eason - Journal of Modern Optics, 1989 - Taylor & Francis
A photorefractive deconvolution process for optical differentiation of images is suggested.
The problems associated with the intrinsic resolution capabilities of this technique, resulting …

Optical implementation of a self-organizing feature extractor

D Anderson, C Benkert, V Hebler… - Advances in …, 1991 - proceedings.neurips.cc
We demonstrate a self-organizing system based on photorefrac (cid: 173) tive ring
oscillators. We employ the system in two ways that can both be thought of as feature …

Photorefractive transport and multiwave mixing

DD Nolte - Photorefractive effects and Materials, 1995 - Springer
The photorefractive effect [1] can loosely be defined as a light-induced change in the optical
properties of a material when the incident light is spatially nonuniform. The spatial …

Transversal parametric oscillation and its external stability in photorefractive sillenite crystals

EV Podivilov, HC Pedersen, PM Johansen, BI Sturman - Physical Review E, 1998 - APS
We develop the nonlinear theory of transversal parametric oscillation in photorefractive
sillenite crystals. The theory is nonlinear in the sense that the nonlinear feedback from the …

The effect of optical bias on grating formation dynamics in photorefractive BSO
