Abstract
An image projector realizing image projection with high image quality by reducing speckle noise. An image projector comprising a coherent light source, a collimation lens for transforming coherent light emitted from the coherent light source into coherent parallel light, and a projection optical system for projecting coherent parallel light is further provided with a reflection element for reflecting the coherent parallel light and capable of oscillating in parallel with the direction normal to the reflection plane, and a reflection element drive means for causing oscillatory motion of the reflection element.

10. An image projector, comprising:
-
a coherent light source; a collimator lens that collimates coherent light from said coherent light source to form collimated coherent light; a projector optical system that projects the collimated coherent light; a reflector element that reflects the collimated coherent light and is capable of vibrating in parallel with a direction normal to a reflector surface of said reflector element; and a reflector element driver unit that drives said reflector element in vibrating motion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
