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 ...

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, ...

Figure 1. Schematic of MMF scanning endoscope based on wavefront shaping principle. The different technical routes, imaging modalities and some key imaging performance metrics of the MMF scanning ...

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 ...

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: ...

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 ...

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 ...

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 ...
