Figure 1: (a) Photography of the miniaturized mid-infrared spectral sensing platform based on metasurface thermal emitters; (b) Thermal image encoding/decoding results of different metasurface thermal ...

The primary source of infrared radiation is heat -- the radiation produced by the thermal motion of charged particles in matter, including the motion of the atoms and molecules in an object. The ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

(Nanowerk News) In an increasingly health-conscious society, data is a hot commodity. Tracking step counts with an old-school pedometer has turned into monitoring heart rates, sleep cycles and blood ...

Experimental setup for computational temporal ghost imaging based on frequency downconversion. Preprogrammed probing temporal patterns generated from the arbitrary waveform generator (AWG) are applied ...
