The iPhone 12 camera is said to receive a number of upgrades, according to one report, with a new set of info detailing that at least one model from the upcoming lineup will feature a rear-facing laser-powered Time-of-Flight 3D sensor. The addition of this camera is expected to improve AR-related experiences and possibly deliver better imaging quality at the same time.

According to a report from Fast Company citing sources that are familiar with Apple’s plans, the iPhone 12 camera will be upgraded thanks to the partnership between the tech giant and Lumentum. The supplier is expected to provide VCSEL lasers that will probably fuel the ‘world facing’ 3D ToF sensor present at the back of the iPhone 12. In case you didn’t know, VCSEL, or vertical-cavity surface-emitting lasers debuted in the iPhone X from back in 2017 but was located at the front to which Apple referred to as the TrueDepth camera for facial recognition purposes.
