Abstract: Systems and methods are provided herein for improved short range object detection in LiDAR systems. The associated systems may include a first portion and a second portion configured to rotate relative to one another. The system may also include a first magnet located on the second portion and arranged with a north pole of the first magnet facing a first direction. The system may also include a second magnet located on the second portion and arranged with a south pole of the second magnet facing the first direction. The system may also include a first sensor located on the first portion. The first sensor is further configured to measure a first magnetic field of the first magnet and a second magnetic field of the second magnet as the first portion and second portion rotate relative to one another.

Abstract: Devices, systems, and methods are provided for using a light detection and ranging (LIDAR) receiver optical design. A vehicle anamorphic LIDAR system may include a group of rotationally symmetric lenses, a first cylindrical lens, and a second cylindrical lens, wherein the first cylindrical lens is arranged between the group of rotationally symmetric lenses and the second cylindrical lens, wherein the vehicle anamorphic LIDAR system is associated with a first focal length in a first direction associated with a scene field of view, and a second focal length in a second direction perpendicular to the first direction and associated with an instantaneous field of view, and wherein the first focal length is different than the second focal length.

Abstract: Devices, systems, and methods are provided for improved heat transfer LIDAR. A LIDAR device may comprise a LIDAR housing configured to attach to a vehicle to detect one or more objects in the field of view of the LIDAR device, wherein the LIDAR housing encloses one or more gases, wherein the one or more gases have a characteristic of being more thermal conductive than air. The LIDAR device may comprise one or more windows allowing light signals to pass through, wherein the one or more windows are attached to one or more walls of the LIDAR housing. The LIDAR device may comprise a rotating platform situated inside the LIDAR housing and configured to rotate around a center axis relative to the LIDAR housing. The LIDAR device may comprise one or more light signal transmitters configured to transmit first light signals through the one or more windows.
