Popis:	We present a method to encode complex values into three or four quantized complex values for wavefront modulation using two digital micromirror devices (DMDs). This encoding offers advantages to eliminate the twin image or suppress the zero order diffraction as well to improve hologram fidelity. The optical architecture utilizes a Michelson interferometer with a DMD in Littrow configuration replacing the mirrors to combine the two holograms with the desired phase shift. System performance was examined using numerical simulations and experimental measurements to explore different encoding methods for hologram reconstruction. Both ZOD and conjugate image suppression were demonstrated for different encoding schemes.
