Abstract:
A color light beam source, comprising:a first light source providing a first light beam of a first color;a second light source providing a second light beam of a second color;a third light beam providing a third light beam of a third color;means for optically distorting the cross-sectional shape of said second light beam to provide a distorted second light beam;means, configured in the optical path of said first and second light beams, for combining the first light beam and second light beam into a first combined light beam having the first light beam and second light beam coaxially combined;means for optically distorting the cross-sectional shape of said third light beam or said first combined light beam; andmeans configured in the optical path of said first combined beam and third light beam, for combining the first combined light beam and the third light beam into an output color light beam having the first combined light beam and the third light beam coaxially combined.
