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. From a series of timed returns, the iPhone can build up a 3D image of what is in front of it.
But there’s a second method which uses a more sophisticated approach …
