TELESCOPE WITH A WIDE FIELD OF VIEW INTERNAL OPTICAL SCANNER
First Claim
1. A telescope with internal scanner comprising:
- a wedge optical scanner comprising a first optical wedge and a controller arranged to control a synchronous rotation of the first optical wedge, the wedge being constructed and arranged to scan light redirected by topological surfaces and/or volumetric scatterers;
a first converging optical element that receives the redirected light and transmits the redirected light to the scanner; and
a second converging optical element within the light path between the first optical element and the scanner arranged to reduce an area of impact on the scanner of the beam collected by the first optical element.

Abstract
A telescope with internal scanner utilizing either a single optical wedge scanner or a dual optical wedge scanner and a controller arranged to control a synchronous rotation of the first and/or second optical wedges, the wedges constructed and arranged to scan light redirected by topological surfaces and/or volumetric scatterers. The telescope with internal scanner further incorporates a first converging optical element that receives the redirected light and transmits the redirected light to the scanner, and a second converging optical element within the light path between the first optical element and the scanner arranged to reduce an area of impact on the scanner of the beam collected by the first optical element.
