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 ...

Various optical systems or geometries can be used to perform light measurements. For instance, the total power [flux] of a light source can be measured in all directions, in a specific direction or ...

Researchers from North Carolina State University 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 ...

Researchers have developed a revolutionary new tool for precision measurement at the nanometer scale in scenarios where background noise and optical loss from the sample are present. (Nanowerk News) ...

In the summer of 1926, an experimental beam of light pierced the night sky between two precisely measured peaks in the San Gabriel Mountains, and science history was made. Virtually unseen by the ...
