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 ...

Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e ...

Sensing with levitated nanoparticles has so far been limited by the precision of position measurements. Now, researchers have demonstrated a new method for optical interferometry in which light ...

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 ...

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 ...

The GRAVITY instrument on ESO’s Very Large Telescope Interferometer (VLTI) has made the first direct observation of an exoplanet using optical interferometry. This method revealed a complex ...
