Abstract: A sensor system can comprise a detector with a plurality of units, wherein the detector is configured to generate a first set of electrical signals based on received photon energy of a light beam that is reflected back from a first plurality of points on one or more objects, in a first configuration. Additionally, the detector is configured to generate a second set of electrical signals based on received photon energy of a light beam that is reflected back from a second plurality of points on one or more objects in a second configuration, wherein the first configuration and the second configuration are with a predetermined correlation. Furthermore, the detector can determine distance to each of the first plurality of points and the second plurality of points on the one or more objects based on the first set of electrical signals and the second set of electrical signals.
