First Claim:
Show all 5 claims |
We claim:
1. A viewing system, comprising:
- a first parabolic profile with an outer reflective surface, the first parabolic profile having a first focal point located within the first parabolic profile and on a symmetry axis about which the first parabolic profile is symmetric;
- a second parabolic profile with an inner reflective surface, the second parabolic profile having a second focal point located within the second parabolic profile and on the symmetry axis, the second parabolic profile being symmetric about the symmetry axis; and
- a light gathering device positioned to gather light passing through the second focal point, said light gathering device being located between said first parabolic profile and said second focal point.
