Light Detection and Ranging or LiDAR is bolstering many sectors like the autonomous vehicle industry and agriculture. After successful field applications, LiDAR is embracing a new age of technological innovation in mobile phones. 

The fourth-generation iPad Pro from Apple has a LiDAR scanner on its rear camera. Although most of the androids include a scanner-less LiDAR in the form of 3D Time-of-Flight sensors in their cameras, there is a significant difference in both techniques. 

LiDAR tracks the position of objects using laser light. It measures the light coming back after hitting any object. It is commonly used to map buildings and terrains. Some advanced LiDAR configuration can even detect the pollutants in the air.

Why LiDAR is chosen to be the newest depth-sensors for phones

The depth sensors in mobile devices such as iPhones can blur the backgrounds in images that are taken with portrait mode. LiDAR, on the other hand, works on the level of individual light photons. It covers a distance up to 16 feet and takes nanoseconds to capture the target. It is more granular and quicker with LiDAR. The device with the LiDAR scanner can map a scene in 3D in all kinds of lighting conditions. 

The scanner-less LiDAR systems on Android phones are flash-based that illuminate the environment using a single pulse of Infra-red light. But the scanning LiDAR system sends a smaller pulse in an area and determine distance using the time of flight. Further, it captures the rest of the area at nanosecond speeds.

One of the most important advantages of scanning LiDAR is that it has a minimum noise level reception. Since it maps the area point by point, you get a more accurate reading. Apple has chosen a solid-state LiDAR instead of bulky rotating LiDARs. It doesn’t have any moving parts and is free from external vibrations. 

LiDAR in the mobile device will allow the users to scan a depth-accurate detection of their surroundings. It works like the front-facing TrueDepth sensor that is optimized for the face. 

From the AR point of view, it makes things even better and allows the work that seems to be impractical with traditional camera sensors. 

It will take a while before we see conclusive results in the form of a more accurate and authentic-looking picture. LiDAR on phones will provide a smarter and faster depth-sensing technology in the near future.
