Abstract:
Interference fringes in a bullseye pattern are produced by a measurement module by interfering a flat reference beam with a spherical beam reflected by a sphere connected to the tip of a probe in point contact with a test object. The bullseye interferogram is registered at a detector and analyzed conventionally to produce a position measurement of the tip of the probe. A beam correction module is used to align the bullseye interferogram with the illumination axis of the measurement module. By combining at least three such measurement modules in a coordinate measurement machine, the three-dimensional position of the probe and of its point contact with the test object can be obtained from analysis of the bullseye interferograms registered by the detectors with high precision and greatly reduced Abbe error.

Claim (Index 8):
A coordinate measurement machine (CMM) comprising:\n at least three interferometric measurement modules configured to emit respective test wavefronts shaped as diverging cones of light; a curved reflective surface placed within said cones of light such that respective bullseye interferograms are produced and sensed by respective detectors, and a processor programmed to produce a three-dimensional position measurement of said reflective surface based on the bullseye interferograms registered by the detectors; wherein the reflective surface is attached to a probe of the CMM and the probe is adapted for three-dimensional motion in point contact with a measured object.
