Understanding LiDAR Technology

What is LiDAR?

LiDAR is a remote sensing technology that uses laser light to create a 3D representation of the environment. It works by emitting laser pulses and measuring the time it takes for the light to return after hitting an object. This time-of-flight measurement is then used to calculate the distance to the object, allowing the creation of detailed depth maps. The precision and accuracy of LiDAR make it valuable in various applications, from autonomous vehicles to surveying and mapping.

How LiDAR Works in Smartphones

In smartphones, LiDAR sensors are miniaturized versions of the technology used in larger systems. These sensors emit infrared light pulses and measure the return time to create a depth map of the surrounding area. This depth map is then used to enhance various features, such as AR applications, photography, and 3D scanning. The integration of LiDAR into Android phones with LiDAR enhances their ability to understand and interact with the physical world.
