ABSTRACT:
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 common excitation input, which is used to cyclically reposition the mirrors between tilted and flat states.
