The optical pitch polishing process has been used over 300 years to obtain high quality optical surface finish with little subsurface damage. A pitch tool consists of a m[...]

A unifying theme of this thesis is the implementation and characterization of point probes for surface metrology. The implementations include two optical non-contact prof[...]

The nature and quality of a surface’s topography can play an important role in a part’s performance and expected longevity. The complexity of a surface topography means t[...]

The advent of sub-aperture computer-numerically controlled (CNC) manufacturing techniques has enabled new opportunities for high-performance optical components and system[...]

Deflectometry has been introduced as a viable alternative to interferometric measurement of specular freeform optical surfaces. Deflectometry measurements show high repea[...]
