A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest movements of a laser beam with extreme sensitivity. Precisely measuring 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 ...

For most of us, the mention of “technological innovation” brings to mind images of the technologies that have become useful for our everyday lives. We imagine aspiring app developers lounging about ...

Focused Laser Differential Interferometry (FLDI) is an innovative, non‐intrusive optical diagnostic tool designed to capture high-resolution density fluctuations within hypersonic flow environments.

Purdue faculty dedicate countless hours to exploring the frontiers of their respective fields, pushing the boundaries of knowledge and contributing to the ever-evolving landscape of academia. To ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime ...

This photograph shows four lasers at ESO’s Paranal Observatory, each one launched from one of the four eight-metre telescopes on site. The launch of these lasers represents a significant milestone for ...

6-axis nanopositioning system assembly provides the ultra high precision required to mount and align optical components to be launched into space, new from PI. Image Credit: PI (Physik Instrumente) LP ...

We suspect there are three kinds of people in the world. People who have access to a Michelson Interferometer and are glad, those who don’t have one and don’t know what one is, and a ...
