LASER LIGHT SOURCE APPARATUS AND IMAGE DISPLAY APPARATUS

摘要

A laser light source device has a laser light source (21) for emitting a laser beam (L), a laser driver (31) for driving the laser light source, a light-collecting lens (24) for collecting the laser beam and reflecting a part of the laser beam, an optical sensor (29) for receiving a reflected laser beam (LS) which has been reflected by the light-collecting lens and outputting a detection signal corresponding to intensity of the reflected laser beam, and a controller (30) for controlling driving of the laser light source by the laser driver (31) in accordance with the detection signal, and the light-collecting lens (24) is disposed in a eccentric-rotated state so that an optical axis of the light-collecting lens (A24) has a tilt (angle ±) with respect to a central ray (L0) of the laser beam (L) being incident on the light-collecting lens.
