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.
Claims18
A sensor apparatus, comprising:
- a source that comprises one or more diodes configured to emit at least one electromagnetic energy beam;
- a reflector configured to reflect the at least one electromagnetic energy beam emitted from the source, the reflector including a plurality of reflective surfaces configured to reflect at least two parts of the at least one electromagnetic energy beam emitted from the source to form at least two reflected electromagnetic beams, the at least two parts being substantially parallel to each other, and the at least two reflected electromagnetic beams being not parallel to each other;
- and
- a receiver configured to receive at least one returned electromagnetic energy beam reflected from one or more objects in an external environment and convert light signals from the at least one returned electromagnetic energy beam to one or more electrical signals, the receiver including a plurality of receiver units, and the plurality of receiver units having a one-to-one correspondence with the plurality of reflective surfaces of the reflector.
An apparatus comprising:
- a source that comprises one or more diodes configured to emit at least one electromagnetic energy beam;
- a reflector configured to reflect the at least one electromagnetic energy beam emitted from the source, the reflector including a plurality of reflective surfaces that are not parallel to each other, and positions of the plurality of reflective surfaces and a position of the source being fixed;
- and
- a receiver configured to receive at least one returned electromagnetic energy beam reflected from one or more objects in an external environment and convert light signals from the at least one returned electromagnetic energy beam to one or more electrical signals;
- wherein the receiver includes a plurality of receiver units, the plurality of receiver units having a one-to-one correspondence with the plurality of reflective surfaces of the reflector.
