A digital micromirror device (DMD) modified for use as a temporal light modulator. The DMD is modified so that the mirrors of the DMD have a preferential tilt direction. The inputs and outputs of the DMD are connected to common ground, except for the bias input lines. The latter are connected to a c ...

David J Mehrl, Kun Pan, Benjamin L Lee: Method and apparatus for using spatial patterns for measuring mirror tilt angles in digital mirror devices. Texas Instruments Incorporated, Charles A Brill, Wade James Brady III, Frederick J Telecky Jr, December 14, 2004: US06831750 (6 worldwide citation)

A method and system for indirectly measuring the tilt angle of micromirrors in a micromirror array. The method and system aims a coherent light beam through an aperture in a screen so that it reflects off of the surface of the micromirror array and creates a pattern of reflected light on the screen. ...
