Optical interferometry has proven to be a very useful tool in providing accurate and precise measurements in many high technology fields. But it is not without its continuing challenges. Optical ...

White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample… ...

“Interferometry can only be performed with data from SAR satellites that are maintained in a very precise orbit,” Pekka Laurila, Iceye chief strategy officer and co-founder, said in a statement.

Because of their ever-increasing use in a variety of applications, microlenses and their design are constantly being improved to reduce distortion, astigmatism, or other problems that can impede ...

To verify the high spatial resolution imaging of the chromatic intensity interferometry, researchers carried out a series of field experiments.

This novel attosecond interferometry has extended the interferometer-based high precision measurement to time-energy domain with an all-optical approach.

Optical cavity enhances interferometry performance 15 Dec 2021 University of Birmingham design could assist delivery of kilometer-scale atom interferometers.

This article looks at the relationship between the drug discovery industry and grating-couple interferometry (GCI).

Why measuring roughness is still a primary reference parameter, and how white light interferometry works.
