Novel synthetic generated hologram system using digital space light modulator

This paper presents a novel synthetic generated hologram (SGH) system, in which a digital micromirror device (DMD) is used as space light modulator (SLM). In the system, the object light beam is directed through a sequence of digital images on a space light modulator, digital micromirror device (DMD), rather than the transparent films used in the conventional SGH. A computer controlled distributing device replace manual operation. With this system, threedimensional full color hologram can be generated by synthesizing a series of two-dimension digital images, obtained by digital camera or generated by computer software. The preliminary experimental results have been obtained with this system. The possible future development has also been discussed.
