Breakthrough could enable cheaper infrared cameras

There's an entire world our eyes miss, hidden in the ranges of light wavelengths that human eyes can't see. But infrared cameras can pick up the secret light emitted as plants photosynthesize, as cool stars burn and batteries ...

Improving molecular imaging using a deep learning approach

Generating comprehensive molecular images of organs and tumors in living organisms can be performed at ultra-fast speed using a new deep learning approach to image reconstruction developed by researchers at Rensselaer Polytechnic ...

The random anti-laser

The laser is the perfect light source—as long as it is provided with energy, it generates light of a specific, well-defined colour. However, it is also possible to create its opposite—an object that perfectly absorbs ...

Putting photons in jail

A miniature prison for photons—that is the nanocavity discovered by scientists of the University of Twente. It is an extremely small cavity surrounded by an optical crystal, a structure of pores etched in two perpendicular ...

New X-ray measurement approach could improve CT scanners

A new measurement approach proposed by scientists at the National Institute of Standards and Technology (NIST) could lead to a better way to calibrate computed tomography (CT) scanners, potentially streamlining patient treatment ...
