Abstract:
Controlling a mirror in a MEMS based projector. A method includes iteratively performing various acts. The method includes inputting a time domain target wave array, with target elements, to a system for a MEMS coupled to the mirror of the projector. The time domain target wave array includes a set of n target elements. The method further includes driving the driver to move the mirror using elements in a drive array comprising a set of drive elements. The method further includes sampling a time domain output wave for the movement of the mirror to construct an output wave array with output elements corresponding to the target elements. The method further includes identifying errors between the target elements and the output elements. The method further includes modifying the drive elements in the drive array to attempt to minimize the errors when driving the MEMS on subsequent drive cycles.
