Patent ID: 8519324

Claim:
A laser projector comprising: a light source for emitting a laser beam; a modulator for modulating the intensity of the laser beam depending on an image to be projected; a vibratory mirror vibratable for horizontally deflecting the laser beam whose intensity has been modulated; a vertical scanning mirror for vertically deflecting the laser beam whose intensity has been modulated; a deflection angle detector for detecting a deflection angle of said vibratory mirror; and a deflection angle adjuster for adjusting the deflection angle of said vibratory mirror based on the detected deflection angle of said vibratory mirror; wherein said deflection angle detector includes a light detecting element array comprising a plurality of light detecting elements arrayed parallel to a horizontally scanning direction along which the laser beam is deflected by said vibratory mirror, said light detecting element array being disposed outside of an image projection area, said light detecting element array including a first light detecting element region, at least both ends of said first light detecting element region disposed outside of the entire horizontal range scanned by the laser beam in a horizontal direction, and including a second light detecting element region disposed inside of the entire horizontal range scanned by the laser beam in a horizontal direction.
