Abstract
A full color 3D projection display using wavelength separation which, through a combination of retarders, prisms and dichroic and polarizing coatings, takes linearly polarized red and green light of p orientation from left and right images and blue linearly polarized light of p orientation from one of the views or a common image, and presents the light for projection having green and red light of one polarization orientation for one view and red and green light of a polarization with another orientation for providing the 3D components of the image. The blue light component is presented alternately in one of both polarization orientations to be perceived with the left and right views, respectively.
