Light-based radar system for augmented reality: United States Patent 9984508

By: Mullins, Brian

A system and method for measuring depth using an optical radar system are described. The system includes an optical radar, a camera, a display, and a processor. The optical radar emits a signal towards an object. The processor identifies an object depicted in an image captured with the camera. The processor generates the signal with a non-repeating pattern of amplitude and frequency, and computes a depth of the object based on a difference in phase angle between the signal emitted from the optical radar and a return signal received at the optical radar. The depth includes a distance between the optical radar and the object. The processor generates AR content based on the identified object and adjusts a characteristic of the AR content in the display based on the computed depth of the object.
