Scientists in Switzerland have developed an ultra-thin metalens that converts invisible infrared light into visible light by ...

A couple of years ago, Light ... 16 lenses. Ten or more of them capture an image simultaneously but at different focal lengths and the camera then combines those separate images into a single ...

"We wanted to design a single planar lens with a high numerical aperture, meaning it can focus light into a spot smaller than the wavelength," said Mohammadreza Khorasaninejad, a postdoctoral ...

The technique, which the researchers have dubbed "light-field moment imaging," allows single lens cameras to produce 3D images, however, not all cameras will be up to the job. The crucial factor ...

The contact lens technology uses nanoparticles that absorb infrared light and convert it into wavelengths that are visible to mammalian eyes (e.g., electromagnetic radiation in the 400–700 nm ...

However, both Yokoyama and Wu note that the results were measured using a monochromatic laser, and say that the lens would probably encounter problems with broadband light. “A single glass lens has a ...

In the reflex design scheme, light travels through a single lens and a mirror is used to reflect a portion of that light through the view finder - hence the name Single Lens Reflex.

Light Fields ... that there is a single opening that exists somewhere behind the array, depending on the angle. Note that this virtual opening persists “between” lenses; something not possible ...
