Here Are The Two Ways 3D Depth Sensing Could Work On The Iphone 8
With growing speculation that a rumored 3D sensor on the iPhone 8 will be used for augmented reality applications, a Barclays research note has described the two different ways this could work. Based on supply-chain reports, Barclays believes Apple actually intends to use a combination of the two. The simplest way to sense 3D space is to use what the note calls Time of Flight (ToF). An emitter transmits a signal (for example, in infrared) and times how long it takes to bounce off an object in front of the iPhone and return to a sensor....
