Citing sources familiar with Apple's plans, Fast Company reports the tech giant has tapped San Jose-based Lumentum to supply the lasers that will sit at the heart of the "world-facing" 3D depth sensor. Apple currently relies on Lumentum for the lasers in TrueDepth, the front-facing camera system which powers Face ID, Animoji and other features on iPhone and iPad.

Unlike TrueDepth, the forthcoming system is expected to calculate depth with time of flight (ToF) technology.

TrueDepth, introduced with iPhone X in 2017, deduces depth by using an infrared VCSEL transmitter and specialized receiver alongside a traditional color RGB camera module to measure deviations in structured light — a pattern of dots — projected across a user's face. The system rumored for 2020 generates a depth map by calculating the time it takes laser light pulses to bounce off a target. Compared to TrueDepth, ToF systems are generally viewed as more accurate and viable over longer distances. The latter consideration is important for a system designed to measure a user's world.
