Apple is working on a rear-facing 3D sensor for future generation iPhones, according to a new Bloomberg report. A 3D sensor on the back of the iPhone would be helpful in augmented reality applications. Apple is evaluating a different technology from the one it currently uses in the TrueDepth sensor system on the front of the iPhone X, the people said. The existing system relies on a structured-light technique that projects a pattern of 30,000 laser dots onto a user’s face and measures the distortion to generate an accurate 3-D image for authentication
Why Apple Could Be Working on Another iPhone X Laser Sensor
Apple’s iPhone X already has a front-facing 3D sensor to identify a person’s face, but it might have plans to add a similar one in the future.
