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 ...

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 ...

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 ...

Figure 1. Schematic diagram of the racemic metasurface. (a) Arbitrary polarization-wavefront conversion. (b) Racemic "super-units". Chirality is one of the fundamental phenomena widely present in ...

Publications of the Astronomical Society of the Pacific, Vol. 130, No. 992 (2018 October), pp. 1-13 (13 pages) Although extreme adaptive optics (ExAO) systems can greatly reduce the effects of ...

Researchers have devised a novel technique to 'flip' the optical wavefront of an image for both polarizations simultaneously, so that it can be transmitted through a multimode fiber without distortion ...

Australian-US team says wavefront-shaping of input light lifts power threshold for SBS scattering by an order of magnitude. A narrowband laser beam shaped by a spatial light modulator excites many ...

WaveFront Dynamics Inc., an ophthalmic medical device company, announced today the commercial launch of its dynamic aberrometry measurement system, the WaveDyn Vision Analyzer. The WaveDyn Vision ...

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 ...
