title: Quad-phase-only filter implementation.
abstract: Some of the fastest commercially available coherent spatial light modulators are binary. This fact has motivated research on the binary phase-only filter, which is unfortunately unable to represent a complex filter function. A technique is introduced here with which a single binary device can be used to represent a complex filter with independent binary representation of real and imaginary parts. The technique is analyzed theoretically, and simulation and laboratory results are presented.
