TECHNOLOGY TO SUPPORT THE COEXISTENCE OF MULTIPLE INDEPENDENT LIDAR SENSORS

Systems, apparatuses and methods may provide for technology that initiates one or more optical pulses in accordance with a first emission pattern, obtains a second emission pattern in response to one or more of a time-variable trigger or a deviation of one or more received optical reflections from an expected reflection pattern, and initiates one or more optical pulses in accordance with the second emission pattern. Moreover, infrastructure node technology may detect, based on an interference notification from a first sensor platform, a deviation of received optical reflection(s) from an expected reflection pattern, select emission parameter(s) in response to the deviation, and alter a first emission pattern with respect to the selected emission parameter(s) to obtain a second emission pattern.

Method and device for optically measuring distances

In order to improve the failure proneness of methods or devices for optically measuring distances, it is proposed that the measurement pulses for measuring distances are sent out aperiodically.

CLOSE RANGE INTERFERENCE REDUCTION
20240230861 · 2024-07-11 ·

The disclosure herein describes reduction of undesired signals within reflected signals of a light detection and ranging (LiDAR) system. For example, a current injection circuit can inject an interference reduction current into an optical detector. Further, for example, an adjustable detection threshold may be adjusted during an undesired signal time period. Still further, for example, a switch can be used to disconnect various detection circuitry to avoid or mask undesired signals.

Laser source assembly with thermal control and mechanically stable mounting

A laser source (340) that generates an output beam (354) that is directed along a beam axis (354A) that is coaxial with a first axis and orthogonal to a second axis comprises a first frame (356), a laser (358), and a first mounting assembly (360). The laser (358) generates the output beam (354) that is directed along the beam axis (354A). The first mounting assembly (360) couples the laser (358) to the first frame (356). The first mounting assembly (360) allows the laser (358) to expand and contract relative to the first frame (356) along the first axis and along the second axis, while maintaining alignment of the output beam (354) so the beam axis (354A) is substantially coaxial with the first axis. The first mounting assembly (360) can include a first fastener assembly (366) that couples the laser (358) to the first frame (356), and a first alignment assembly (368) that maintains alignment of the laser (358) along a first alignment axis (370) that is substantially parallel to the first axis.
