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 ...

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: ...

Broadband achromatic wavefront control, a cornerstone of next-generation photonic systems that supports full-color imaging, multi-spectral sensing ...

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 ...

(a) Schematic illustration of the proposed signal modulation process. Left: initial input laser spot illustration before interacting with the SLM and Si metasurface. Middle: schematic of the linear ...

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, ...

Gravitational-wave detection technology is poised to make a big leap forward thanks to an instrumentation advance led by physicist Jonathan Richardson of the University of California, Riverside. A ...

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 ...

Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...

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 ...
