Projector system with light pipe optics |
摘要 |
A projector system includes a lamp, a reflector collector optic, relay optics to image the light from the light pipe exit pupil to the image gate, a light pipe and an image forming means such as a film gate or an LCD (Liquid Crystal Display) panel. The light pipe has a round or octagonal entrance pupil, reflecting internal walls, is tapered in shape, and has a rectangular exit pupil which is larger than a center section in cross-section. The light pipe mixes the light, by internal reflection, and produces light which is uniform in color and intensity across the exit pupil.
