How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Commercial near-infrared (NIR) and visible light Optical Coherence Tomography (OCT) of the same eye. Compared to commercial NIR OCT, visible light OCT achieves fivefold finer axial resolution, which ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...

Researchers have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the lasers can be precisely tuned and extremely fast -- up to ...

Researchers have developed a low-cost visible light communication (VLC) system using commercially available hardware that ...

On a flyby of Venus, NASA’s Parker Solar Probe captured the first visible light images of the cloudy planet’s surface from space, a new study reports. The nightside view of the extremely hot surface ...
