Citing a source with knowledge about Apple's new iPhones, Fast Company writes that Apple will introduce a rear-facing 3D sensor array to new iPhone models. Apple plans to buy the laser components for this array from Lumentum, the California-based company from which it already buys the front-facing TrueDepth lasers found in today's iPhones.
