  A single-pixel digital holography system with phase-encoded illumination
using a digital micromirror device (DMD) as a spatial light modulator (SLM) is
presented. The enhanced switching rate of DMDs, far exceeding the stringent
frame-rate of liquid crystal SLMs, allows recording and reconstruction of
complex amplitude distributions in just a few seconds. A single amplitude
binary modulation device is used for concurrently displaying the phase-encoded
sampling patterns, compensating the distortion of the wavefront, and applying
phase-shifting, by means of computer generated holograms. Our detection system
consists of a simple photodiode that sequentially records the irradiance
fluctuations corresponding to the interference between object and reference
beams. The system recovers phase and amplitude information even when a diffuser
is placed in front of the photodiode.
