BPOF composite filter optimized with a genetic algorithm

Kotynski Rafal, Chalasinska-Macukow Katarzyna

Abstract

We introduce a new composite Fourier-plane binary phase-only correlation filter (BPOF). The filter is defined with the use of a nonquadratic energy function and is optimized numerically with a variant of the genetic algorithm. A possible application of the filter could include automatic postcode recognition. The paper also contains an introduction to composite filtering and a short overview of the present state of technology in the field of coherent optical correlators.
