ABSTRACT:
This invention discloses a reflective illumination system for supplying an optical radiation beam along a folded path for illuminating a planar object. The system includes a radiation source, and two facing parabolic dish-shaped arrays of parabolic or dished reflectors. Divergent light received from the light source incident on a first of the arrays is reflected as a larger collimated beam comprising plural separated sub-beams. Each of the reflectors or facets from the first array directs one of the sub-beams to a facet on the second array. The second array reflects the light it receives with a substantially uniform intensity onto a rectangular target location.
