Abstract

Phase-only filters are attractive designs because they provide good noise resistance and fairly narrow peaks together with optimum light efficiency. Since they contain only phase information they are easier to implement in current spatial light modulators. However, their extension to the synthetic discriminant function (SDF) formalism is troublesome owing to the nonlinear constraints involved. We developed a new procedure for computing phase-only SDF filters which is intended to overcome some of the pitfalls of previous methods.
