Abstract

A systematic procedure is presented for designing optimal correlation filters for implementation on deformable mirror devices (DMDs) exhibiting cross-coupled amplitude and phase characteristics. The utility of the algorithm for designing such filters is illustrated using five different device characteristics: phase-only filter, a binary phase-only filter, a diagonal line characteristic, a DMD zeroth-order characteristic, and a DMD first-order characteristic. Results are also presented regarding the signal-to-noise ratio and peak-to-correlation energy obtainable using these filters. The performance achievable using DMD type characteristics was found to be close to that of phase-only filter.
