METHOD FOR SCANNING SPACE WITH A LASER BEAM AND DETERMINING THE COORDINATES OF DETECTED OBJECTS Russian patent published in 2023 - IPC G02B26/08 G01S17/88 

FIELD: detecting spatial objects.

SUBSTANCE: method for scanning space with a laser beam and determining the coordinates of detected objects, including the formation of a helical sweep of the beam by two identical optical wedges installed in series along the beam, rotating by two drives, the helical sweep is formed by rotating the wedges in one direction, applying linearly increasing angular setting actions to the inputs of the drives, simultaneously setting the rotation of the same wedges in different directions at an angle equal to the angular radius of the scanning field multiplied by the optical reduction of a pair of wedges, applying additional linearly increasing angular input actions of opposite signs to the drive inputs in antiphase, synchronizing the start of the reciprocating motion task in each cycle of the beam with zero readings of the wedge rotation angle sensors, when the beam is being scanned, the actuators are controlled to work out the setting actions using the wedge rotation angle sensors, the coordinate of the detected object in the scanning field is determined based on the polar coordinates using angle sensors, and the polar coordinates of the object are converted into coordinates in the Cartesian system.

EFFECT: improvement in the operational characteristics of the tire.
