Abstract: A laser projector compatible with wavelength multiplexing passive filter techniques comprises a scanning system and a plurality of laser systems, wherein each output beam of light has a unique wavelength and is similar in hue to at least one other output beam of light, wherein the output beam of light is received and deflected by a scanning system to produce stereoscopic 3D images on a projection surface. The integrity of the inherent properties of coherent laser light sources, in particular collimation, monochromacity, and speckle, is maintained, contributing to the unique appearance of the resulting stereoscopic images.
