Paper Abstract

We design a multichannel polychromatic nonzero-order joint transform correlator (NOJTC). The system is implemented using a general JTC scheme by the design of an ideal reference function and additional power-spectrum subtraction strategy for a multichannel correlator. We test the performance for noise and distorted images in the input. In addition, the introduction of various numbers of images in the training set is investigated. The multichannel polychromatic NOJTC shows better detection ability over conventional systems.
