Graphene infrared (IR) photodetectors enable ultrafast and room temperature IR cameras ultrasensitive for entire spectrum, and 3D cameras

Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation. There is a wide variety of photodetectors that may be classified by mechanism of detection, such as photoelectric or photochemical effects, or by various performance metrics, such as spectral response. Photodetectors are devices that measure photon flux or …

Military applications of Ultravoilet spectrum becoming feasible with Technology breakthroughs

The electromagnetic spectrum is a series of frequencies ranging from radio waves to microwaves, visible light, X-rays, and gamma rays. As the wavelength of the electromagnetic radiation shortens, the waves have a higher frequency—how quickly electromagnetic waves follow each other—and therefore more energy.   Ultraviolet (UV) is electromagnetic radiation with …
