Abstract
A method for light detection and ranging that includes forming a first light pattern within a region of a scene by holographic projection. The first light pattern includes n light spots arranged in a regular array. A light return signal is received from each light detection element of an array of light detection elements directed at the region of the scene. The intensity of the light return signals is assessed. If the light return signals do not meet at least one signal validation criterion, a second light pattern is formed within the region of the scene by holographic projection. The second light pattern includes m light spots arranged in a regular array, wherein m≠n. A time-of-flight in association with each light spot of the second light pattern is then determined.
