Compact hybrid video color mixer for large-area laser projection display

The present paper relates to an optical module of a compact hybrid video color mixer for large-area laser projection display. The compact optical arrangement gives a very small- sized and high-performance video image color mixing apparatus which uses a hybrid R/G/B color separator, modulate the light beam using a 3-channels acousto-optic modulator according to the video image signal and combines the modulated R/G/B beams to one beam using a hybrid R/G/B color combiner. A high performance video image projection apparatus can be realized using a light source, a hybrid video color mixer and a X-Y scanner set. The present hybrid video color mixer is suitable for a future domestic laser TV application.
