Abstract
Primary colors red, green and blue are each transmitted in three adjacent frequencies to create stereoscopic 3D images. A true center frequency for each primary color is transmitted to one eye while two straddling frequencies, on either side of the center frequency, are transmitted to the other eye. Untinted, notch filtered stereoscopic 3D eyeglasses may be used to segregate light frequencies and direct one channel to each eye of the viewer. A new dual channel laser illumination projection engine may be used to homogenize, condense, combine, and polarize light from red, blue and green lasers to create stereoscopic images suitable for projection on either white of sliver screens.
