Optical aberration theory remains a fundamental component in the design and operation of space telescopes. With increasingly ambitious astronomical missions and the demand for high-resolution imaging, ...

This paper covers a discussion of the Abbe Sine Condition and its implication for Flat Optics, including the effects of stop shift and substrate curvature. Following that, we apply Sweatt’s high index ...

Depth sensing plays a crucial role in various applications, including robotics, augmented reality, and autonomous driving. Monocular passive depth sensing techniques have come into their own for their ...

Not an aberration: schematic drawing of the metalens (left), which is made of tiny titanium waveguides. The drawing on the right is of a single waveguide. (Courtesy Boubacar Kanté) A new type of ...

Optical aberrations and the errors they introduce are a standard obstacle in localization microscopy techniques, and hinder the gathering of depth information from a biological sample. A project at ...

The latest aberration-corrected electron microscopes can resolve individual atom columns in a silicon crystal that are just 78 pm apart. How many students are told, perhaps during their first science ...

Aspheres allow designers to build smaller, lighter and simpler optical systems, and can be found in everyday products. Edwin Diaz provides a back-to-basics guide to the technology. You may not realize ...

NASHVILLE, Tenn. — Wave-guided optics application technology may now help patients with keratoconus, according to a speaker at Optometry’s Meeting. “We know a lot of our irregular cornea patients ...

Researchers invented a new type of microscope called reflective matrix microscope, which uses adaptive optics techniques. Non-invasive microscopic techniques such as optical coherence microscopy and ...
