Abstract:
A method of creating a full color image, the method comprising the steps of:providing a white light beam to a first prism, said white light beam entering a first face of said first prism and traveling to a second face of said first prism; reflecting a first primary color portion of said white light beam and passing a first remainder portion through said second face of said first prism and a first face of a second prism, said reflected first primary color portion exiting said first prism through an exit face; modulating said first primary color portion to reflect a modulated first primary color portion to said second face of said first prism; reflecting a second primary color portion of said first remainder portion at a second face of said second prism to exit an exit face of said second prism; passing a third primary color portion through a third prism to exit an exit face of said third prism; modulating said second and third primary color portions to reflect modulated second and third primary color portions to said second face of said second prism; focusing said first, second, and third modulated primary color portions onto an image plane; and further filtering at one said exit face to block light modulated at another exit face.
