Barclays also expects Time of Flight sensors on the back of next year’s “Pro” models
With ToF technology, infrared signals are sent out to a subject and the time it takes for them to bounce off and return to the phone is counted. From this data, 3D maps and more reliable depth information can be generated. This should lead to an enhanced and more realistic bokeh blur on portraits, improved AR effects, and a rear-facing version of Face ID. Unlike the TrueDepth Camera system that Apple employs for Face ID at present, it reportedly will turn to VCSEL (vertical-cavity surface-emitting laser) for the ToF sensor. This could allow Apple to offer a secure facial recognition system that scans faces as far away as 15-feet compared to the 25 to 50 centimeters range available with Face ID.
