OPTICAL SYSTEM WITH ARRAY LIGHT SOURCE

摘要

An optical system (1600), projector and method are provided that include a projection gate (1660) between a light source array (1620) and a projection lens (1670). The projection lens projects an image of the projection gate. A relay lens group (1630) between the light source array and the projection gate prevents the projection lens from projecting an image of the light source array. A lamp housing (1640) is provided for use with a projector housing (1660). The lamp housing includes a light source array and a relay lens group located between the light source array and a projection gate in the projector housing. An illumination source (1900) for optical fibers (1918) is provided that includes a relay lens group (1930) between a light source (1920) and a coupling (1924) in a housing (1902). The relay lens group prevents an image of the light source from being formed at input ends (1922) of optical fibers positioned in the coupling.
