1. A method of controlling a mirror in a MEMS based projector, the method comprising iteratively performing the following:
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 comprising a set of n target elements;
driving a driver to move the mirror using elements in a drive array comprising a set of drive elements;
sampling a time domain output wave for movement of the mirror to construct an output wave array with output elements corresponding to the target elements;
identifying one or more modifications to make to the drive elements in the drive array by calculating errors between the target elements and the output elements based on an impulse response for each output element determined by individually driving the input of the driver with an impulse input for each of the drive elements in the drive array; and
modifying the drive elements in the drive array based on the identified one or more modifications to make to the drive elements in the drive array.
