Abstract
An imaging system comprising a parabolic reflector having a base and defining a first axis, a light source disposed proximate the base essentially along the first axis, an imaging device comprising a zooming lens having a second axis, the imaging device being disposed in front of the light source along the first axis such that the second axis and the first axis are essentially coincident.
Claims22
An imaging system having a forward and rearward orientation, said system comprising:
- at least one parabolic reflector having a base and a focus, and being configured to substantially collimate light;
- at least one a light source disposed near or essentially at said focus of said parabolic reflector forward of said base and being configured to emit light toward said at least one parabolic reflector such that said at least one parabolic reflector collimates said light to emit substantially collimated light;
- and
- an imaging device disposed forward of said at least one light source and comprising a zooming lens having an optical axis essentially parallel with said substantially collimated light, said imaging device configured to image a field of view along said optical axis forward of said imaging device and away from said at least one light source.
