The use of two-level phase masks or spatial light modulators in confocal imaging systems is considered. It is shown how, although such masks can modify or correct the effective point-spread function of a system, their behavior for planar objects may not be as desired as a result of phase-wrapping effects. Overcoming this problem with a multilevel mask or a pair of two-level masks is discussed.
