Abstract
An apparatus has a first emitter emitting at a first frequency optical pulses that form a first pulse collection. A second emitter emits at a second frequency optical pulses that form a second pulse collection. A first receiver collects during a time of flight time window a first reflected pulse collection corresponding to the first pulse collection reflected from a sensed object. A second receiver collects during the time of flight time window a second reflected pulse collection corresponding to the second pulse collection reflected from the sensed object. A processor analyzes the first reflected pulse collection and the second reflected pulse collection to produce first reflected pulse collection metrics and second reflected pulse collection metrics.
