Abstract

Selon la présente invention, dans un dispositif (1) de source lumineuse, les positions où une lumière laser traverse un élément (15) d'émission de lumière peuvent être balayées à l'aide d'un miroir (16) à entraînement à modulation de motif dans un dispositif (4) de balayage optique. Des sections (15a) de non émission de lumière sont agencées selon un motif prescrit sur l'élément (15) d'émission de lumière et le motif des sections (15a) de non émission de lumière dans une région d'émission de lumière de la lumière laser est modifié par la position de la lumière laser. Ainsi, le motif de brillance de la lumière laser change au cours du temps et même si la lumière laser provenant du dispositif (1) de source lumineuse est diffusée par un écran (P), une interférence dans la rétine humaine est supprimée, permettant à un bruit speckle d'être réduit. De plus, dans le dispositif (4) de balayage optique, une lumière laser est balayée par le miroir (16) à entraînement à modulation de motif ; ainsi, le motif de brillance de la lumière laser peut être modifié de manière stable par comparaison avec la situation dans laquelle un élément (15) d'émission de lumière lui-même est entraîné à haute vitesse.
