First Claim
Patent Images
1. A sensor system for retroreflecting a laser beam, said system having a retroreflective surface comprising:
- a series of reflective cubes;
a series of microtriple reflectors, being formed by three adjacent square faces on the corner of a reflective cube; and
a series of equilateral hexagons formed by a surface on said microtriple reflectors, wherein the distance between two parallel facing sides in said hexagons is between 0.002 mm to 1.4 mm, and the microtriple reflectors are positioned so that a laser beam simultaneously contacts at least five microtriple reflectors on the retroreflection surface.

Abstract
The invention relates to a sensor system based on the retroreflection of a laser beam comprising a retroreflection surface having a series of microtriplet reflectors. The sensor system has individual micro reflector elements that are formed by the three adjacent square surfaces of a cube corner. The individual micro reflector elements have a cross sectional area similar to an equilateral hexagon having a width over flats of 0.002 to 1.4 mm. With this design, the laser beam simultaneously contacts at least five microtriplets on the surface of the retroreflector.
