This is a subject close to my own heart - I was slightly involved in an earlier iteration of very similar research. The aim is to find out how rich or poor people are in remote or otherwise ...

Always on the lookout for better ways to measure all kinds of things, researchers have published a detailed study suggesting an "elegant" improved definition for the standard unit of light power, the ...

Researchers have developed a new tool for detecting and measuring the polarization of light based on a single spatial sampling of the light, rather than the multiple samples required by previous ...

Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision. These electro-optic Fabry-Pérot resonators will ...

Human vision relies on light. After reflecting off surfaces, light enters into the eyes and travels through the cornea and pupil to produce an image on the retina. The eye is sensitive to a broad ...

Laser Doppler vibrometers (LDVs) measure vibrations in ways that other sensors can't. From large aircraft structures to microscopic MEMS sensors, and vacuum enclosures to red-hot mills, LDVs measure ...

Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision. The researchers are from the Department of ...
