ABSTRACT:
A high definition image projector is provided for modulating light using an acousto-optic tunable filter according to image signals and projecting the modulated light on a screen. An image is obtained by modulating a light beam by pixel units according to the image to be displayed and directly projecting the modulated light beam on the screen in corresponding pixel units. High quality images can thus be displayed on a large screen. By adopting a high-output light source, a high luminance image can be obtained.
