It then detects the return flash using an array of sensors called single-photon avalanche diodes (SPADs) supplied by Sony.

Repeat this process across a two-dimensional grid and the result is a three-dimensional "point cloud" showing the location of objects around a room, street, or other location.Ī June analysis by System Plus Consulting found that the iPad's lidar sends out light using an array of vertical cavity surface-emitting lasers (VCSELs) made by Lumentum.
Because light travels at a constant speed, the round-trip time can be translated into a precise distance estimate. Lidar works by sending out laser light and measuring how long it takes to bounce back. And while no one has done a teardown of the iPhone 12 yet, we can learn a lot from recent iPad teardowns. Apple first introduced the technology with the refreshed iPad in March. Tuesday's presentation offered little detail about how the iPhone's lidar actually works, but this isn't Apple's first device with lidar.
And it may enable the creation of a new generation of sophisticated augmented reality apps. Apple says lidar will enhance the iPhone's camera by allowing more rapid focus, especially in low-light situations. At Tuesday's unveiling of the iPhone 12, Apple touted the capabilities of its new lidar sensor.
