Laser interferometry has emerged as a pivotal technique for precision measurement, utilising the interference of coherent laser beams to detect minute displacements and variations in optical path ...

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 ...

Self-correcting machine tools that not only manufacture parts, but also check the parts’ dimensions – with the Absolute Multiline Technology, the vision of a self-controlled production becomes reality ...

Modern semiconductor manufacturing technology has advanced rapidly. Because of this, measurement using non-contact displacement and transparent coating thickness has become very critical. Applications ...

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 ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

Clever use of quantum feedback and single photons has produced the most sensitive interferometer yet devised, with a precision approaching the Heisenberg limit. Interferometers detect the differences ...

When we think of physics experiments, we tend to envision cavernous rooms filled with things like optical benches, huge coils in vacuum chambers, and rack after rack of amplifiers and data acquisition ...

Researchers have moved a step closer to achieving quantum-noise-limited measurements using laser interferometry – a technique routinely employed for detecting the motion and displacement of tiny ...
