Apple Inc. (AAPL - Get Report)  is already looking ahead, not two weeks after its groundbreaking iPhone X was released.

The tech titan is reportedly exploring the possibility of a rear-facing 3D sensor system for the iPhone to be released in 2019. A new rear-facing system would enrich the augmented reality experience on the company's flagship mobile device, according to a report from Bloomberg citing unnamed sources familiar with plans.

The new sensor system would be different from Apple's front-facing Face ID technology it unveiled in the iPhone X this fall. That system, which uses TrueDepth technology, projects structured light onto the user's face to measure distortion and generate a 3D image for authentication.

The planned new technology, though, would instead use a time-of-light approach to calculate how long it takes for a laser's light to bounce off an object in order to create a 3D replication of the environment, Bloomberg reported.

Apple is expected to keep the TrueDepth technology for front-facing 3D sensors, meaning future iPhones could have both front- and rear-facing 3D sensor technology. Time-of-light sensor manufacturers include Infineon Technologies AG (IFNNY) , Sony Corp. SNE, STMicroelectronics NV (STM - Get Report)  and Panasonic Corp. (PCRFY) .
