Abstract

A method for optical correlation is discussed that can use a liquid crystal television in the filter plane. Conventional binary phase-only filtering is compared with a binary amplitude approach that uses the sum of the intensities from multiple binary amplitude correlations. One parallel processing implementation is presented that uses three binary amplitude filters, each filter using a different wavelength of light. A computer simulation using synthetic filters shows that a binary amplitude multiple wavelength filter (BANE) that uses ternary phase correction works as well as a conventional binary phase-only filter when used as a scale invariant filter and as a synthetic estimation filter.
