Patent ID: 7133204

Claim:
A display system, comprising: a beam generator operable to generate a light beam of first and second wavelengths; and a diffraction grating operable to receive the light beam from the beam generator and to, generate from the first wavelength first beamlets of at least first, second and third orders, each first beamlet having approximately a first intensity, simultaneously generate from the second wavelength second beamlets of at least the first, second, and third orders respectively, a second beamlet of the first order having a second intensity and the second beamlets of the second and third orders each having approximately a third intensity, superimpose the first beamlets of the first, second, and third orders on the second beamlets of the first, second, and third orders, respectively, to generate a resulting beamlet of the first order having a fourth intensity and resulting beamlets of the second and third orders having approximately a fifth intensity, wherein the fourth intensity is greater than the first and second intensities, and wherein the fifth intensity is greater than the first and third intensities but less than the fourth intensity.
