Adaptive optics (AO) systems play a pivotal role in mitigating the deleterious effects of atmospheric turbulence and optical aberrations, thereby enhancing the resolution and imaging quality in fields ...
Discover how high-speed wavefront sensing enhances space situational awareness by overcoming atmospheric distortion.
Yes, it can! This is one facet of adaptive optics, which astronomical observatories can use to compensate for distortions in astronomical images caused by our atmosphere. Let’s set the stage first: ...
Researchers at Caltech make progress in medical imaging by adapting astronomical optics. A reflector shapes light waves to counterbalance distortion. Researchers in Caltech’s Andrew and Peggy Cherng ...
New York, NY—May 8, 2023—Researchers at Columbia Engineering have developed a new class of integrated photonic devices--“leaky-wave metasurfaces”--that can convert light initially confined in an ...
Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, which can be useful, but it also creates chromatic aberrations. As bandwidth ...
A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250149, discusses a quarter-wave geometric-phase route ...
ABSTRACT The corrected field of view of an adaptive optics system is thought to provide a severe limitation on the usefulness of an adaptive optics system. We show that under good seeing conditions, ...
Optical Surfaces Ltd is a manufacturer of large output beam expander optics enabling interferometers to be used for testing of large optical flats up to 600mm in diameter. Large output beam expander ...
These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record ...
