Patent
CA 2144304
An image mover having a reduced sizing for the steering mirror and rotator assembly and associated com- ponents and motors is disclosed. The image mover (10) comprises a relay lens (18) to collimate and relay angular information of the light image from the projector scanning mirror (16). Rotators, such as K-mirror, pechan prism, or dove prism, rotate the collimated image responsive to horiz- ontal movement of the image. A restoring lens (22), which can either be a fixed focal length or a zoom lens, restores the collimated light image proportional to the angular in- formation of the image produced by the projector. The res- tored diverging image is projected to a steering mirror (24) and steered onto a viewing surface (26) in real time.
