Each array of five PCSEL beams is linked to a dichroic mirror, which causes near-infrared light to be split up into distinct beams of different wavelengths, which are then combined by another ...

It measures the absorption of infrared light by a sample at different wavelengths to produce a spectrum that provides information about the sample's molecular structure and composition. Schematic ...

Free-space optical communication, or FSO, is an interesting and easy way to transmit signals through light beams. Forget expensive ... like a TV remote-control infrared LED and a photo diode.

Schematic representation of infrared spectroscopy. First, a beam of IR light from the source is split into two and passed through the reference and the sample respectively. Now, both of these beams ...

A Japanese research team has "seen the light" and is utilizing infrared wavelengths to generate electricity, an untapped energy source that accounts for nearly half of solar energy striking the Earth.
