| Title: |
Optical System With Array Light Source |
| Abstract: |
An optical system, projector and method are provided that include a
projection gate between a light source array and a projection lens. The
projection lens projects an image of the projection gate. A relay lens
group 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 is provided for use with a projector housing. 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 for optical fibers is provided that
includes a relay lens group between a light source and a coupling in a
housing. The relay lens group prevents an image of the light source from
being formed at input ends of optical fibers positioned in the coupling.
