A projection apparatus creates laser generated visible images utilizing the interference of light principle, and includes individual laser projection devices, positioned and disposed in opposite sets, each structured to emit a select color laser beam which is modified and split by optical phase modulators and beam splitters, respectfully, to form an array of beams which intersect with beams from the oppositely disposed laser projectors to produce the desired multi-colored image. The apparatus is supported above or below the desired area of the generated image with the laser devices mounted on computer controlled motorized swivel mounts, providing the capability to selectively locate the produced images at various preprogrammed locations within a defined area.
