Photomultiplier Tube

A photomultiplier tube is actually a type of vacuum tube, sensor designed to scan for very weak lightsources. It gets its name from the way it works ? it senses incoming photons, and replicates them, multiplying the number of photons several times before a detector picks up the hue, and intensity of the signal.

They are used in medical imaging, and some types of security installation. They would be ideal for VR applications such as detecting movement on the inside edge of HMDs. However, their bulk and their large power requirements prevent that. Solid state photomultipliers, do not suffer the same limitations.

Phone that recognises tube stops
This podcast is a three-minute snippet from BBC News, hailing the advent of augmented reality. It was broadcast on UK national TV in August 2009, so it missed the actual advent of AR by about 60 years, and the public?s uptake by about a half decade. Still, it serves as an excellent introduction to the topic.
