Several techniques can be used for the optical implementation of correlation filters onto spatial light modulators whose coding domain has a limited extent. Using the general framework of optimal trade-off filters, we compare them in the case of a 4f architecture and demonstrate that oversampling certain parts of the filters can improve performance.
