ABSTRACT:
A video display system includes a laser beam that is reflected from a vertical scan rotating mirror, then from a horizontal scan rotating mirror and then toward a viewing surface. The rotational angles of the mirrors and the intensity of the laser are controlled by a controller that is driven by a video signal. Rotation of the horizontal mirror scans the laser beam across the viewing surface while the laser intensity is modulated to form pixels on the viewing surface. The vertical scan mirror then directs the beam to the next horizontal scan line. The resolution and aspect ratio of the image are adjusted by changing the rotation rate of the mirrors and by changing the rate at which the laser is modulated.
