Laser projector for projecting and displaying an image based on the raster scanning of a laser beam

摘要

A laser projector displays an image based on raster scanning of a laser beam. The laser projector is capable of reliably detecting the deflection angle of a vibratory mirror used for horizontally scanning without the need for a light source other than a laser light source for displaying images even if the deflection angle is small, and also of accurately adjusting the deflection angle of the vibratory mirror to a predetermined deflection angle at the resonant frequency of the vibratory mirror without exceeding the predetermined deflection angle.
