When the liquid level is above the prism, light passes through, but when it’s below the top it reflects more IR light back into the table. Using this information, restaurant staff could serve ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be ...

This novel detector transforms incident infrared light into ultra-confined “nanolight” in the form of phonon polaritons within its active area. This process serves two critical functions ...

Back when he was first starting out in electronics he built this infrared-controlled light switch that works with a standard TV remote control. [Vadim]’s first few projects ended up as parts for ...

From your smartphone’s face recognition feature to fancy fitness trackers and advanced night vision cameras, many sensors we use daily rely on infrared light detection. For the last eight years ...

Recently, the group of Prof. Labao Zhang of Nanjing University, together with the group of researcher Haiyong Gan of the National Institute of Metrology, China, have developed a new thermal radiation ...

Infrared light requires line of sight to its destination ... that obstruct the line of sight required by infrared. An IR sensor is located near the TV and wired to the receiver, which can be ...

The IG26H series from Laser Components expands the existing lineup of high-quality IG26 extended InGaAs infrared (IR) PIN ...

Infrared (IR) light is a type of electromagnetic radiation ... "This first-ever mid-IR detection, and the variability seen with the SMA, has not only filled a gap in our understanding of what ...

Prof Zhang Zhiyong's team at Peking University developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with a recorded ...

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 are reflected to pass through a splitter and then ...

Known as Sgr A* – pronounced “Sagittarius A star” – the supermassive black hole is four million times the mass of the sun and is known to exhibit flares that can be observed in multiple wavelengths, ...
