System and method for integrated, analog mode mirror devices
First Claim
1. A method for controlling a position of a micromirror, the method comprising:
- receiving a value, wherein the position is based on the value and the position of the micromirror is between a first stop position and a second stop position;
determining a drive waveform based on the value; and
providing the drive waveform to the micromirror.

Abstract
A system and method for integrated, analog mode mirror devices. A system containing integrated, analog mode mirror devices includes a damped digital micromirror device (DDMD) optically coupled to a light source and positioned in a light path of the light source, and a controller electrically coupled to the DDMD. The damped micromirrors move more slowly than undamped micromirrors, thereby enabling control of the position of the micromirrors by the controller, with the position being in a range of positions between a first stop position and a second stop position. The micromirror may be moved to a position when presented with a drive waveform that has been modulated by a value specifying the position. This enables the specifying and control of the position of the individual micromirrors in the DDMD.

11. A system comprising:
-
a first damped digital micromirror device (DDMD) optically coupled to a light source and positioned in a light path of the light source, the first DDMD comprising an array of micromirrors operating in a damping liquid, wherein the damping liquid retards the movement of the micromirrors; and a controller electrically coupled to the first DDMD, the controller configured to provide drive waveforms to individual micromirrors in the first DDMD, wherein a drive waveform moves the micromirrors in the first DDMD to a position between a first stop position and a second stop position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
