Abstract: Systems and techniques associated light detection and ranging (LIDAR) applications are described. In one representative aspect, techniques can be used to implement a packaged semi-conductive apparatus is disclosed. The apparatus includes a substrate; a diode die carried by the substrate and positioned to emit an electromagnetic energy beam; and a shell coupled to the substrate to enclose the diode die. The shell includes an opening or a transparent area to allow the electromagnetic energy beam emitted from the diode die to pass through the shell.

Abstract: The present disclosure provides a laser diode package module. The laser diode package module includes a substrate including a first surface; a cover disposed on the first surface of the substrate; an accommodation space formed between the substrate and the cover; a laser diode die disposed in the accommodation space; and a reflective surface disposed in the accommodation space for outputting light of the laser diode die reflected by the reflective surface and transmitted through a light-transmitting area. The light-transmitting area is at least partially disposed on a surface of the cover opposite the substrate.

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.
