A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...

Users of iPhone 12 and later may have noticed the black dot near the lens. This is the LiDAR sensor that emits lasers and is ...

There are a whole bunch of different ways to create 3D scans of objects these days. Researchers at the [UW Graphics Lab] have demonstrated how to use a small, cheap time-of-flight sensor to generate ...

Photoelectric sensors and light curtain sensors are among the most commonly used sensing devices in factories. Photoelectric sensors are mainly used to detect parts products or material movement.
