Texas-Instruments phase-light-modulator (TI-PLM) is composed of a 2D array of micro-mirrors that move in a piston motion by a fraction of wavelength to modulate the optical path length of a beam. Such light phase modulation, which is required for holography, could be a promising alternative to the liquid crystal-based spatial-light-modulators (SLMs). In comparison, TI-PLM has better diffraction efficiency, enlarged reflection angle, reduced pixel size, and faster refresh speed which expands the spatial bandwidth. All these properties benefit the recording of complex holograms. We demonstrate the successful use of TI-PLM to record a variety of such holograms.
