Researchers use laser light to form a tiny “optical pinhole” inside a nonlinear crystal, which also turns the infrared image into a visible image that a traditional silicon-based camera sensor can ...
Infrared thermal cameras can noninvasively measure the surface temperatures of objects and are widely used as fever-screening systems for infectious diseases. However, body temperature measurements ...
Researchers have developed an innovative photodetector capable of detecting a broad range of mid-infrared spectra. NASA's James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to ...
Physicists have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices ...
