Paper Abstract

The utility of updatable optical image correlation in photorefractive materials for industrial applications is discussed. This allows the formation of iterative correlation products employing variable spatial frequency weighting and/or different reference images. Several aspects of the system design are discussed, including techniques for producing spatial frequency weighting and optimum laser systems to maximize data throughput and output stability.
