Paper Abstract

An all-optical wavelet processor for target detection has been developed and demonstrated at JPL. An innovative 2D Shape-discriminant wavelet filter, encoded with a ternary-valued scheme, was developed and implemented in a Liquid Crystal Television Spatial Light Modulator (LCTV SLM) to enable real-time updatable processing. Applications ranging from flight object discrimination, mine detection, and cancer cell detection have been demonstrated.
