ABSTRACT:
A full color display optical system with chromatic aberration correction. The system includes a wide spectral band image source such as a cathode ray tube or Ferroelectric liquid crystal array, a field sequential Red-Green-Blue shutter, and an optical module for projection. The optical module corrects longitudinal chromatic aberration and higher order monochromatic and chromatic aberrations. Lateral chromatic aberration and chromatic distortion are compensated electronically by the color sequential shutter and the image source with a pre-distorted image.
