Cube Corner Retroreflector For Measuring Six Degrees of Freedom

摘要

A target and method of manufacturing the target is provided. The method of manufacturing includes providing the cube cornered retroreflector, the cube cornered retroreflector including a first, second and third 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 method further including the step of directing ions from a focused ion beam etching (FIBE) device onto the first intersection junction defined by the first planar reflector and second planar reflector. A first material is removed from at least a first portion of the first intersection junction to define a first non-reflecting portion.
