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.
