Abstract

The aim of this work is an advancement of digital holographic interferometry by using a digital micromirror device (DMD) for real-time display of interferometric fringes. The theory describing the formation of the diffractedimage produced by a coherently illuminated DMD is presented. Digital holograms of simple structures are calculated assuming plane and spherical reference waves, respectively. These synthetic holograms are used to control themicromirrors of the DMD, which now acts as a reflective hologram. Experimental holographic reconstructions of synthetic holograms prove the feasibility of DMDs in principle for this aim. Further experimental results show thereconstructed interferogram of fields recorded by digital holography and superposed numerically. This opens a new range of applications in digital holographic interferometry. (C) 2001 Society of Photo-Optical InstrumentationEngineers.
