In the latest iPhone Pro models, users have been curious about a mysterious black circle next to the camera array. This circle can also be found in certain iPad Pro models and serves a very useful purpose, unlocking some of the device’s coolest apps and features.
This black dot is actually a LiDAR scanner, which stands for Light Detection and Ranging. It acts as a depth sensor, utilizing lasers to determine the distance of objects. By emitting a pulsed laser and measuring the time it takes for the light to return, the iPhone or iPad can create a 3D model of the surrounding environment.
LiDAR technology has been pivotal in discovering hidden cities in the Amazon by digitally uncovering ruins beneath the forest canopy. It is also widely used in self-driving cars to gauge the distance between vehicles. However, in iPhones, it enables advanced photography and augmented reality apps that can accurately sense the distance of objects.
Apple’s Measure app, for instance, harnesses the power of LiDAR to measure lengths, widths, and areas with incredible precision. It can even measure a person’s height using the LiDAR sensor. The Measure app has been enhanced with additional features such as vertical and edge guides for quicker and more accurate measurements. Users can also save a list of measurements along with screenshots for future reference.
Moreover, the LiDAR sensor greatly enhances the camera capabilities in the Pro models, particularly in low-light conditions. It improves autofocus speed and accuracy, resulting in better quality photos.
There are numerous apps that take advantage of LiDAR technology. Polycam, for instance, is a 3D scanner that swiftly creates virtual models of objects and spaces using the LiDAR sensor. This can be used for fun or even for room planning purposes. Additionally, LiDAR enables augmented reality apps where virtual objects interact with the real world. IKEA Place, an example of such an app, allows users to place virtual furniture within their homes to see how well they fit.
In conclusion, the mysterious black circle present next to the camera array on the latest iPhone Pro models and certain iPad Pro models is actually a LiDAR scanner. This powerful depth sensor employs lasers to accurately measure distances and is integral to advanced photography, augmented reality apps, and innovative features like measuring height.
