In modern iPhone phones, a strange black dot is observed on the back, which is located near the camera, but it is not similar to any of the other lenses, and there are 4 iPhone models that have this point on the back, including iPhone 12 Pro, iPhone 12 Pro Max and iPhone 13 Pro And the iPhone 13 Pro Max, and it is possible that the expected iPhone 14 will come with it as well.
Some wondered what this point is and why it is on the back of the phone? And in this report we answer those questions, according to the British newspaper, The Sun.
LiDAR Scanner
The black circle is actually a LiDAR scanner. LiDAR stands for Light Detection and Ranging. It is designed to measure distances, and works by sending a beam of light to the subject and timing how long it takes to return.
through sensor The phone can determine what it is focusing on and measure what is in front of it. This means that the iPhone can accurately create a 3D map of the space in front of the sensor. This can be used for photography, to enhance augmented reality in applications, and for some other smart features.
Apple supplies devices Iphone A pre-installed app that uses the LiDAR scanner in a very clever way. Just swipe down from the top of the screen to pull up the search bar and type Measure, and it will pop up an app that opens the viewfinder, from which you can use it to measure any real-world object with amazing accuracy.
Lots of apps you use
Measure isn’t the only app that uses the scale. Lots of apps use LiDAR to improve their AR features, Ikea Place lets you place furniture in your home so you can see what it’s going to look like, and Canvas lets you take a 3D picture of an entire room. You can use them in virtual tours, and other applications.
