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 design of the human eye introduces a number of potential optical aberrations, unique to an individual, which then impact on both vision testing and accurate retinal imaging. Monochromatic ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

Microscopy is the workhorse of contemporary life science research, enabling morphological and chemical inspection of living tissue with ever-increasing spatial and temporal resolution. Even though ...

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 ...

The word 'aberration,' meaning a departure from the ordinary, highlights life's deviations. Originating from Latin for 'to wander away,' it describes irregularities in science, optics, and human ...
