What is a LiDAR scanner, the iPhone 12 Pro’s camera upgrade anyway?



The iPhone 12’s camera specs have finally been revealed – and we now know that the iPhone 12 Pro range will use the new LiDAR scanner on the back. That’s right, the same mysterious point that first appeared on the 2020 iPad Pro.

But what is a LiDAR scanner? A built-in lie detector? A more relaxed version of radar, perhaps? As we shall see, LiDAR (or “Light Detection and Ranging”) works in a similar way to radar, but only uses lasers to assess distances and depths. This is big news for augmented reality (AR) and, to a lesser extent, photography.
