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 ...

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 ...

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 ...

Laser interferometry is a technique allowing for contactless dimensional measurements of high precision with a dynamic range of several meters in air and nanometric resolution. It is used for ...

Abstract: We describe some aspects of a method for detecting indirect laser light (the weak off-axis or back-scattered radiation of a laser beam scattering in the atmosphere or from a rough surface) ...

Cambridge Technology, based in Taunton in the United Kingdom, is a manufacturer of precision Beryllium mirrors. The company recently outlined how employing best-in-class interferometry hardware and ...

Abstract: Speckle interferometry, as a high-precision, non-contact, and highly sensitive optical non-destructive testing method, has been widely applied in fields such as defect detection, quality ...
