Abstract:

The patent describes an optical system using a concentric Bouwers lens having in the converging beam another lens to create parallel light paths to the concentric point of the Bouwers lens. At such concentric point, a mirror directs the light to the side. Upon reversal of the light paths, a parallel light beam or laser enters the system from the side, through the assembly to a target, and then back to the starting point where it is detected.
