For more than 50 years, phase-shifting interferometry has been the technology of choice for high-precision surface form ...
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 ...
Focused Laser Differential Interferometry (FLDI) is an innovative, non‐intrusive optical diagnostic tool designed to capture high-resolution density fluctuations within hypersonic flow environments.
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 ...
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 ...
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 ...
