A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest ...

Laser interferometry has emerged as a leading non‐contact method for the precision measurement of gear geometries. By utilising the interference of coherent light, these systems can detect minute ...

A laser interferometer is the classic instrument of choice for measuring and compensating CNC machines and CMM machines in order to minimize downtime and make them more cost-efficient. CENTRIC ...

A quantum trick based on interferometric measurements allows a team of researchers to detect even the smallest movements of a laser beam with extreme sensitivity.

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

A heterodyne interferometry system with a fiber-optic sensor was developed to measure the temperature history of unburned gas in an engine cylinder. A polarization-preserving fiber and metal mirror ...

The quantification of large optics demands metrology systems that operate in the context of turbulence, vibration and additional challenges. Figure 1. Measurement of large optics, such as this 8-meter ...

The new, compact AccuFiz® Fizeau laser interferometer offers an unmatched combination of performance, quality and value, for high accuracy shape and transmitted wavefront quality measurements of ...

Fringe conference can be traced to the automatic processing of fringe patterns. The term “patterns” evokes an image of flowing lines elegantly wrapped around surface contours. However, automatic ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...
