Mirror control circuitry described herein is for controlling a first micro-mirror of a micro-mirror apparatus that scans across a target area in a scan pattern. The mirror control circuitry includes a processor that determines a mechanical angle of the first micro-mirror for a given instant in time during scanning of the first micro-mirror between upper and lower rotational limits, the mechanical angle being such to maintain the scan pattern as being uniform while the micro-mirror apparatus scans across the target area between the upper and lower rotational limits. The processor also generates a driving signal for the first micro-mirror as a function of the determined mechanical angle for the first micro-mirror at the given instant in time.
