Abstract

An innovative multispectral pattern recognition system, consisting of a surface plasmon tunable filter (SPTF) and a compact Grayscale Optical Correlator (GOC) is under development at JPL. The surface plasmon tunable filter is capable of rapidly acquiring narrowband input imagery sequence through the visible spectral band (400nm-1000nm) and feed into the cascading GOC for parallel target recognition. The combined system will be useful for one-pass hyperspectral imaging and pattern recognition.
