Abstract

A pulsed light source illuminates a scene with a virtual array of points. Light reflected by the scene is detected by a small pixel array, allowing generation of a three-dimensional map of the scene. A processing element processing data output by the small pixel array uses a multipath resolution algorithm to resolve individual objects in the scene.
