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 ...

Very-long baseline interferometry (VLBI) is a technique in radio astronomy whereby multiple radio telescopes cooperate to ...

The ESO (European Southern Observatory) has announced the successful observation of an exoplanet using optical interferometry. It's the first time an exoplanet has been "seen" in this manner and the ...

Large-scale atom interferometers, analogous to optical interferometers but measuring the difference in phase between atomic matter waves on different paths, are intended to be key elements in future ...

A team of astronomers from the U.S. Naval Observatory (USNO), Naval Research Laboratory (NRL) and the European Southern Observatory (ESO) have successfully used the ultra high-resolution capability of ...

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 ...

Optical Surfaces Ltd has received an order from Armstrong Optical, a leading UK supplier of optical metrology instruments, to supply high specification transmission and reference flats for a custom ...

For more than 50 years, phase-shifting interferometry has been the technology of choice for high-precision surface form ...
