I have always been fed up with using Augmented Reality apps and games on my smartphones as the experience is really terrible. When Apple announced that the new iPad Pro will feature a LiDAR sensor for better AR capabilities, I was thrilled, to say the least.

Apple promised way better AR performance for the new iPhones along with camera improvements as well. So, What is Apple’s LiDAR Scanner? Let's find out.

This news made me jump on the hype train and check the new iPad Pro’s and iPhone 12 Pro’s prowess with the LiDAR sensors. And when I got to use them, I was surprised at how much better the experience was compared to devices without a dedicated LiDAR sensor for AR.&nbsp,

After going through Apple's official documents and subjecting various Apple devices to stress tests, my team and I found that:

Apple's LiDAR Scanner is a time-of-flight (ToF) scanner that uses laser light to measure the distance to objects. This allows it to create detailed 3D models of the world around it. The LiDAR Scanner is found in devices like the iPhone 14 Pro and Pro Max, iPad Pro (2020), and is even the key component in the upcoming Vision Pro's Spatial Computing capabilities.

Read on to know more about LiDAR and Apple’s implementation of it in the iPhone 12 Pro lineup and iPad Pro (2020) lineup.&nbsp,

What is LiDAR?

Light Detection And Ranging (LiDAR) is a technology that uses lasers to scan and map surroundings. This is similar to how radar, the difference is that radar uses radioactive waves while LiDAR uses light waves. Check out our "What is Apple’s LiDAR Scanner?" guide for all the details.

And Radar is used for faraway objects while LiDAR is used for close-by objects because light gets absorbed easily. It is similar to ultrasonic imaging used by bats to see.&nbsp,&nbsp,

A LiDAR sensor emits hundreds of thousands of light pulses every second, LiDAR can scan the distance and sizes of objects over small ranges. The data collected by the sensors is used to create 3D models, one of the best uses of LiDAR in construction and engineering in recent years.&nbsp,

LiDAR is now used in self-driving cars, for the detection of objects and people. It is also available in automatic vacuum cleaning robots. In the yesteryears, LiDAR was used in military tech and astronomy.

LiDAR in Apple devices&nbsp,

With innovation and technological advancements, LiDAR has improved. The scanners have become cheaper, smaller, and more accurate over time. This is helped LiDAR find its way into mobile devices like tablets and phones.

• Phones have been using Time-of-Flight (ToF) sensors for a similar purpose, but Apple went one step further and has introduced LiDAR for its iPads and iPhones. The reason was for better and more accurate distance imaging. Check out our "What is Apple’s LiDAR Scanner?" guide for all the details.

• The Apple iPad Pro (2020) and iPhone 12 Pro models have LiDAR technology in them. They enable better photography, Augmented Reality (AR), and 3D modelling capabilities for the devices.&nbsp,

List of Apple Devices That Support LiDAR

Here's the catch, not every iPhone in existence supports the LiDAR functionality. Only a handful of devices come with this unique feature and they are the,

• iPhone 14 Pro
• iPhone 14 Pro Max
• iPhone 13 Pro Max
• iPhone 13 Pro
• iPhone 12 Pro
• iPhone 12 Pro Max
• iPad 2020 Pro (iPad Pro 12.9 inch 4th gen, iPad Pro 11 inch 2nd gen)
• iPad Pro 2021 13 inch

LiDAR in iPhones and iPad

The way LiDAR is implemented on Apple devices is different when compared to other industry implementations. It uses the same principle, to find the distance between objects but in a shorter range.

• LiDAR on iPhones and iPads have an effective range of 16 feet (5 meters). It works both indoors and outdoors and allows for spatial tracking (tracking the location of people and objects around you).&nbsp,&nbsp,

• Apple wants the LiDAR scanners in its devices to provide you with unparalleled Augmented Reality (AR) experience, better camera capabilities and create 3D maps of your immediate surroundings.

• The LiDAR sensor with Apple’s primary cameras and processing capabilities, Apple intends to give you the best AR experience on a phone. Apple wants to move away from the popular Time-of-Flight (ToF) sensor found in other smartphones and Apple thinks LiDAR is the way forward.

• ToF uses a single pulse of infrared light whereas LiDAR uses hundreds of thousands of light pulses in a short period, and this is what more effective than ToF sensors. LiDAR gives better range and better depth and distance mapping information.&nbsp,

• And true to the word, the AR experience on the iPad Pro and iPhone 14 Pros are simply classes above other smartphones, there’s literally no competition in this regard. This also opens up for more future innovations for more apps and games can take advantage of this technology.

• All this is possible and speedy only because of the processing capabilities of the Apple devices that use LiDAR. The A12Z Bionic found in the iPad Pros and the A16 Bionic found in iPhone 14 Pros enable for this process to happen fast enough so that there is no delay and there is no poor user experience in using LiDAR.

• As of now, the only limiting factors seem to be the sensors itself as they lack resolution for more detailed workflows. But this will be improved and for a first-generation implementation, the LiDAR scanners in the current set of devices work really well in boosting AR performance.&nbsp,&nbsp,

And in reality, Apple’s intention and use case for their LiDAR sensors was for AR gaming and applications and some camera improvements.&nbsp,&nbsp,

Use of LiDAR in Apple Devices

Apple also said that every existing ARKit app will benefit from the new LiDAR scanners. This will improve the speed, occlusion, tracking, and motion capture for ARKit apps.

An update to the ARKit to the new Scene Geometry API will allow developers to benefit from LiDAR scanners in their apps. Check out our "What is Apple’s LiDAR Scanner?" guide for all the details.

• The AR experiences of games like Pokémon Go and apps like Snapchat are leaps and bounds better on Apple devices featuring the LiDAR scanner compared to other smartphones and tablets. Hot Lava is a game that uses Apple’s LiDAR scanner to bring molten rivers to your home.&nbsp,

• Ikea’s Place app also is really cool to take on AR and it allows you to check how their furniture's would look in your home. This is like a real-life version of The Sims but it is helpful nonetheless aiding you in purchasing the best furniture for your home.&nbsp,&nbsp,

• LEGO also has launched products that come alive when scanned via your smartphone. And undoubtedly these all work excellently on the new iPad Pros and iPhone 14 Pros.&nbsp,

• Apple’s own Measure app now is improved because of the LiDAR scanners. It is now faster and easier to calculate a person's height with the Measure app.

• It also increases accuracy and helps you measure objects as well with guidelines for easier reading. The Measure App now has a Ruler view for more close and accurate measurements and you can save the measurements with screenshots for each measurement.&nbsp,

• Apple has said that the low light performance of cameras in the new iPhone are helped because of LiDAR. Apple’s ‘Focus Pixels’ (similar to Phase Detection AutoFocus PDAF) from iPhone XS depends on the light in the environment for good results and since at night there is not enough light, this autofocus method didn’t work so well.

• This is where LiDAR will aid in camera performance. LiDAR can tell the image processor to focus at the correct distance for the best results. This helps for better photos in the dark when combined with the already excellent Night mode.&nbsp,

Does the Apple Vision Pro Come Equipped with a LiDAR Scanner?

Yes, the Apple Vision Pro is equipped with a LiDAR scanner. This feature enhances the device's spatial awareness and computational capabilities.

The LiDAR scanner employs time-of-flight technology, using laser beams to measure the distance between the device and surrounding objects.

This produces highly accurate 3D models of the environment, which can be invaluable for various applications like augmented reality (AR), virtual reality (VR), and 3D modeling tasks.

Another advantage of the LiDAR scanner on the Vision Pro is its ability to function effectively in low-light conditions. This makes it particularly useful for AR applications where lighting may vary.

Furthermore, the Vision Pro comes with a TrueDepth camera system that offers functionalities like facial recognition, eye tracking, and hand tracking.

Combined with the LiDAR scanner, this technology suite enables the Vision Pro to deliver a rich, interactive, and immersive AR experience.
