Through a Sensor, Holographically

(PhysOrg.com) -- The power and resolution of lens-based optical microscopes have improved by orders of magnitude since their invention around 1595. Nevertheless, relying on a high-magnification lens for image clarity has ...

Engineering team invents a camera that powers itself

A research team led by Shree K. Nayar, T.C. Chang Professor of Computer Science at Columbia Engineering, has invented a prototype video camera that is the first to be fully self-powered—it can produce an image each second, ...

Toshiba smartphone camera sensor has eye on future

(Phys.org)—Toshiba may be targeting the end of 2013 for the launch of a new camera sensor for smartphones and tablets, where the picture taker can choose a specific area of focus in the photo after having taken the photo. ...

LuminAR bulb lights path to augmented reality (w/ video)

(Phys.org)—Are we moving closer to a computer age where "touchscreen" is in the room, but it is the counter, desktop, wall, our new digital work areas? Are we moving into a new form factor called Anywhere? Do we understand ...

3-D, after-the-fact focus image sensors invented

(PhysOrg.com) -- At the heart of digital photography is a chip called an image sensor that captures a map of the intensity of the light as it comes through the lens and converts it to an electronic signal.

Color-sorting metalenses boost imaging sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...
