Near-infrared (NIR) photon detection and object recognition are crucial technologies for all-weather target identification. Conventional NIR detection systems that rely on photodetectors and von ...

LOS ANGELES (Reuters) - NASA plans next month to launch a space telescope that will scan the heavens for the infrared glow of celestial objects never seen because they are too dim, dusty or distant, ...

Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure shows an infrared ...
