Precision surface measurement.

Surface size, geometry and texture are some of the most influential subjects in the fields of precision and ultra-precision engineering, defining the functional interface through which emerging products operate. Next-generation products demand super-smooth surfaces, freeform geometries or even deterministically introduced microstructures to provide functional performance. Technological progress...

3-D Precision Surface Measurement By Dynamic Structured Light

This paper describes a 3-D imaging technique developed as an internal research project at Southwest Research Institute. The technique is based on an extension of structured light methods in which a projected pattern of parallel lines is rotated over the surface to be measured. A sequence of images is captured and the surface elevation at any location can then be determined from measurements of ...

Multi-Camera-based High Precision Measurement Approach for Surface Acquisition

In this paper, a unique 3D shape measurement method for measurement of nearly plain car body parts is proposed. The main advantage of the system is the high accuracy (about 0.1 mm), the high flexibility and the real-time processing. The primary application of the method is the 100% inspection of press formed car parts in the factory since in these cases the high accuracy and the real-time featu...

Environment-assisted precision measurement.

We describe a method to enhance the sensitivity of precision measurements that takes advantage of the environment of a quantum sensor to amplify the response of the sensor to weak external perturbations. An individual qubit is used to sense the dynamics of surrounding ancillary qubits, which are in turn affected by the external field to be measured. The resulting sensitivity enhancement is dete...

Finite Precision Measurement

Only nite precision measurements are experimentally reasonable, and they cannot distinguish a dense subset from its closure. We show that the rational vectors, which are dense in S 2 , can be colored so that the contradiction with hidden variable theories provided by Kochen-Specker constructions does not obtain. Thus, in contrast to violation of the Bell inequalities, no quantum-over-classical ...
