Abstract:
A two-panel color modulation device comprising:a beam splitting element; an input polarization rotation element that rotates a first light spectrum's polarization differently than a second light spectrum's polarization; a chromatic polarizer optically coupled to the beamsplitting element, wherein the input polarization rotation element and the chromatic polarizer separate the polarization of the first light spectrum from the polarization of the second light spectrum such that the beam splitting element is operable to direct one of the first and second light spectrums in a first direction and is operable to direct the other of the first and second light spectrums in a second direction; a first panel which is operable to receive the one of the first and second light spectrums directed in the first direction from the beam splitting element; and a second panel which is operable to receive the other of the first and second light spectrums directed in the second direction from the beam splitting element, wherein one of the first and second panels sequentially modulates one of the first and second spectrums.
