If you want to get the greatest benefit from a beam of light - whether to detect a distant planet or remedy an aberration in the human eye - you need to be able to measure its beam front information.

A new device designed by optics professor Chunlei Guo and PhD student Billy Lam is a 'revolutionary step forward' for characterizing the properties of laser beams in a much more reliable and powerful ...

Whether it's adjusting a telescope or focusing a laser beam to a small spot, wavefront sensing can help. Xavier Levecq explains the technique and the options available. Measuring the wavefront ...

A super compact interferometer will give scientists an unprecedented ability to fine tune even the quickest pulses of light for a host of applications, and could render traditional instruments for ...
