WASHINGTON -- Researchers report a new imaging system that cancels the chromatic optical aberrations present in a specific person's eye, allowing for a more accurate assessment of vision and eye ...

The use of deformable mirrors to correct unwanted optical aberrations in real time is helping applications ranging from astronomy to biophotonics and data storage, reports Neil Savage. Adaptive optics ...

A new retinal imaging system enables cellular-level imaging even in eyes with significant optical aberrations. Most devices using adaptive optics for retinal imaging are unwieldy and only function in ...

Guide star-free imaging Image of a bee head acquired with a wide-field transmission microscope in the presence of aberrations (left) and after correction (right). The image inserts represent quantum ...

Structured light passing through a noisy environment gets distorted (a), but if another unstructured beam also gains the same distortion, the effect can be undone by mixing them in a nonlinear crystal ...

Fuzz and speckle patterns befit pajamas but are unwelcome in imaging experiments. Biology thus tends to interfere with imaging because living things often absorb, scatter or locally ...

Researchers from the Optics Group at the Universitat Jaume I in Castellón have managed to correct in real time problems related to image aberrations in single-pixel microscopy using a recent ...

Higher order aberrations (HOAs) of the eye are unable to be corrected by cylinder or spherical corrections and include spherical aberrations, coma and trefoil. Coma aberrations are caused when light ...

Adaptive optics is a class of components that can be added to optical systems to improve their performance. They do this by reducing the incoming wave distortions which can arise due to natural ...

For centuries, astronomers looking up at the heavens through a telescope had a problem on their hands – the quality of their images depended on the strength and direction of the wind in the air.
