Color Corrected Projection System with Field of View Expansion Optic

Abstract:

Chromatic aberrations are corrected on a first axis of a lens system by the lens system itself. Chromatic aberrations caused by the lens system on a second axis of the lens system are compensated for by varying the timing of laser light pulses of different wavelengths. In visible projection systems, red, green, and blue laser light pulses for a single display pixel are produced at different times as a function of pixel position.
