An image mover having a reduced sizing for the steering mirror and rotator assembly and associated components and motors is disclosed. The image mover comprises a relay lens to collimate and relay angular information of the light image from the projector scanning mirror. Rotators, such as K-mirror, pechan prism or dove prism, rotate the collimated image responsive to horizontal movement of the image. A restoring lens, which can either be a fixed focal length or a zoom lens, restores the collimated light image proportional to the angular information of the image produced by the projector. The restored diverging image is projected to a steering mirror and steered onto a viewing surface in real time.

A high efficiency light projection apparatus using lasers that optimize all available power output from two lasers to provide a balanced color display is disclosed. The light projection apparatus comprises two laser and light separation means to produce separate red, green and blue light beam components. A combiner cube is provided for combining the blue light beam component of one of the lasers with the blue light beam component of the other laser. Also provided is a second combiner cube for combining a portion of one of the lasers green light beam component with the other lasers green light beam component which combined components are transmitted to a dye laser to provide a red light beam component. Additionally, a light projection apparatus is disclosed that provides convenient access by the operator and presents an overall narrower configuration for the projector for transportation, installation and alignment purposes.
