Abstract:
A scanning projector includes a mirror that scans in two dimensions, at least one of which is sinusoidal. A position sensor provides a position signal that represents an angular displacement of the mirror. The position signal is amplified by an amplifier with time variant characteristics. A beam position determination component compensates for the time variant characteristics of the amplifier.
