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 ...

An unsatisfying compromise has to be made between acceptable throughput and sufficient data coverage when measuring high-slope machined parts, since metrology tools usually involve some sort of ...

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 ...

In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations. The production of these complex-shaped ...

Researchers have developed a revolutionary new tool for precision measurement at the nanometer scale in scenarios where background noise and optical loss from the sample are present. (Nanowerk News) ...

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 ...

Around 1.8 billion years ago, in a distant galaxy, two vast black holes spiraled into each other, and their cataclysmic merger sent ripples through the very fabric of the universe. On August 14, 2017, ...
