Evaluation of measurement technique for a precision aspheric artefact using a nano-measuring machine [PDF]

, 2013
A precision aspheric artefact is measured in 3D by a commercially available nano-measuring machine (NMM) integrated with a contact inductive sensor as the probe. The mathematics of 3D compensation of the error caused by the probe radius is derived.
