Abstract: Systems and techniques associated light detection and ranging (LIDAR) applications are described. In one representative aspect, techniques can be used to implement a sensor device. The sensor device includes an electromagnetic energy emitter module positioned to emit an electromagnetic energy beam directed to one or more objects, a beam steering module positioned to receive at least a portion of the electromagnetic energy beam that is reflected from the one or more objects, and an array of receiver units positioned to convert the portion of the electromagnetic energy beam into multiple electrical signals. The beam steering module is further positioned to direct the portion of the electromagnetic energy beam to the array of receiver units, with individual receiver units positioned to detect multiple optical signals from the portion of the electromagnetic energy beam and convert the multiple optical signals into electrical signals.
