Abstract
A light detection and ranging (LIDAR) system for a vehicle can include: a light source configured to output a transmit beam at a first orientation; a reflective surface configured to redirect the transmit beam from the first orientation to a second orientation; and a lens interface configured to receive the transmit beam at the first orientation and focus the transmit beam onto the reflective surface; wherein the LIDAR system emits the transmit beam at the second orientation into an environment of the LIDAR system.
Claims20
A method for manufacturing a semiconductor-based light detection and ranging (LIDAR) system for a vehicle, the method comprising:
- providing a light source, the light source configured to output a transmit beam;
- forming a reflective surface on a substrate that is generally parallel to the transmit die such that the reflective surface is configured to redirect the transmit beam from a first orientation that is substantially coplanar with the transmit die to a second orientation that is substantially normal to the first orientation and emit the transmit beam at the second orientation into an environment of the LIDAR system;
- arranging a transmit die to provide the transmit beam from the light source to the reflective surface;
- and
- disposing a receiver photonics die in the LIDAR system such that the receiver photonics die is configured to receive a received beam from the environment of the LIDAR system.
