Paper Abstract

An alternate spatial weighting scheme is given for creating synthetic reference objects (SROs) for use in joint optical correlation. The objects are spatially weighted using an aggregate of pixels made up from the objects composing the SRO. An ad-hoc iterative algorithm is presented for finding a workable SRO. The algorithm is demonstrated by using it to find a spatially weighted scale invariant SRO for a random object. The SRO is then compared with a conventional transmission weighted SRO using linear and nonlinear spatial light modulator models. The spatially weighted SRO was found to be more robust with respect to modulator nonlinearities.
