Abstract:
1. A laser projector, comprising: a laser light source; and a deflection apparatus that deflects light from the laser light source by a reflection member in a first scanning direction and a second scanning direction that are orthogonal to each other, and that scans a projection surface two-dimensionally, the laser projector displaying a two-dimensional image on the projection surface by adjusting an output of the laser light source according to a deflection state of the deflection apparatus, wherein the deflection apparatus scans faster in a first scanning direction than in a second scanning direction, wherein the deflection apparatus deflects light from the laser light source to thereby project light onto the projection surface obliquely in the second scanning direction, wherein, assuming that a screen-center display state of the deflection apparatus is a deflection state in which a ray from the laser light source is deflected by the deflection apparatus to be incident on a center of the projection surface, and that a positive direction in the second scanning direction is a direction in which an incidence angle of a ray deflected by the deflection apparatus on the projection surface increases, light from the laser light source is incident on the deflection apparatus from a negative direction side in the second scanning direction, and a normal line of the reflection member of the deflection apparatus in the screen-center display state is tilted toward the negative direction side in the second scanning direction with respect to a normal line of the projection surface.
