"Scanning Depth Engine
Today the U.S. Patent Office granted Apple their third patent for a "Scanning Depth Engine" under number 10,261,578. Apple's patent covers their invention related to methods and devices for projection and capture of optical radiation, and particularly to optical 3D mapping. The mapping apparatus includes a transmitter, which is configured to emit a beam including pulses of light, and a scanner, which is configured to scan the beam, within a predefined scan range, over a scene.

You could review our report covering Apple's second granted patent for this invention in general here. You could review today's newly granted patent here. The fine addition to Apple's invention could be found in their patent claim #4 which now mentions their transmitter comprises a laser.
In January Bloomberg reported that "Apple Inc. plans to launch iPhones with a more-powerful 3-D camera as soon as next year, stepping up the company’s push into augmented reality, according to people familiar with the plans.
The rear-facing, longer-range 3-D camera is designed to scan the environment to create three-dimensional reconstructions of the real world. It will work up to about 15 feet from the device, the people said. That’s in contrast with the current iPhone 3-D camera system, which points toward users and operates at distances of 25 to 50 centimeters to power Apple’s Face ID facial-recognition feature.
Apple’s new system uses a laser scanner, rather than the existing dot-projection technology which doesn’t work as well over longer distances."
