Abstract:
A scanning laser projector includes a scanning mirror that moves in a sinusoidal motion on at least one axis. Pixels are displayed by modulating a laser beam that is reflected by the scanning mirror. Pixels are generated using light pulses of different duty cycles based on the position and/or angular velocity of the laser beam.
