LIDAR SYSTEMS AND METHODS Russian patent published in 2023 - IPC G01S17/00 

FIELD: lidar systems.

SUBSTANCE: present technology relates to lidar detection and ranging systems (LiDAR, Light Detection and Ranging) and to methods for detecting objects in the surrounding space of an autonomous vehicle, in particular to lidar systems and methods for detecting objects in an area of interest of the surrounding space. Essence: a lidar system for detecting objects in the surrounding space of an autonomous vehicle contains a radiation source configured to emit output beams along the internal radiation path, and a scanner located on the internal radiation path and capable of directing the output beams to an area of interest within the field of view. The scanner comprises a first reflective surface capable of receiving at least a portion of the output beams and transmitting it as a first propagating beam along the first propagation axis, and a second reflective surface capable of receiving at least a portion of the output rays and transmitting it as a second propagating beam along the second propagation axis, different from the first propagation axis, while the region of interest contains the first part defined by the first propagating beam, the second part defined by the second propagating beam, and the third part between the first and second parts, which is a blind zone.

EFFECT: maximum increase in the width of the region of interest located relative to the vehicle by allowing a blind zone in its middle, as well as providing the ability to quickly and efficiently switch from one region of interest to another due to selective scanning of regions of interest.
