NPL Brings Frequency Scanning Interferometry to Large-Scale Manufacturing

Frequency scanning interferometry uses a tunable laser to provide highly accurate distance measurements. It was first developed by researchers at the University of Oxford who were working on the Large Hadron Collider at CERN. They needed a way to measure tiny movements of the particle detectors and there was no existing measurement technology that could provide the required accuracy over the tens of meters of the detector array. The system they developed used columnated laser beams. These had to…
