One of the oldest problems in optics has been solved. Rafael Gonzalez from Mexico's Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely ...

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, ...

Figure 1. Shown here is the same degree of pincushion (a positive geometric distortion) for a 4:3 aspect ratio image and a 16:9 aspect ratio image. The percentage of distortion is visibly greater in ...

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 ...

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 ...

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 ...

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 ...

Quantitative phase imaging (QPI) is a microscopy technique widely used to investigate cells and tissues. Even though first biomedical applications based on QPI have been developed, both acquisition ...

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 ...
