Cube corner retroreflector for measuring six degrees of freedom
First Claim
1. A target comprising:
- a cube corner retroreflector including three planar reflectors, each planar reflector capable of reflecting light, each planar reflector perpendicular to the other two planar reflectors, each planar reflector intersecting the other two planar reflectors in a common vertex, and each planar reflector having two intersection junctions, each intersection junction shared with an adjacent planar reflector for a total of three intersection junctions within the cube corner retroreflector; and
a non-reflecting portion of each intersection junction, wherein, for at least one intersection junction, the non-reflecting portion is wider in a first region than in a second region.

Abstract
A target includes a cube corner retroreflector including three planar reflectors, each planar reflector capable of reflecting light, each planar reflector perpendicular to the other two planar reflectors, each planar reflector intersecting the other two planar reflectors in a common vertex, and each planar reflector having two intersection junctions, each intersection junction shared with an adjacent planar reflector for a total of three intersection junctions within the cube corner retroreflector. The target further includes a non-reflecting portion of each intersection junction, wherein, for at least one intersection junction, the non-reflecting portion is wider in a first region than in a second region.
