LIDAR WITHOUT MOVING PARTS Russian patent published in 2019 - IPC G01S17/36 

FIELD: optics.

SUBSTANCE: invention relates to the control of laser radiation without moving parts with the ability to control the direction, intensity, frequency and phase characteristics of light radiation and can find application in a number of special areas, in the optical location, control systems of robotic complexes, systems of drivers assistance in vehicles, systems for preventing collision with restrictions, mapping and navigation. Claimed lidar without movable parts comprises a laser emitter, a horizontal linear modulator, a horizontal linear modulator control system, vertical linear modulator, vertical linear modulator control system, transmitting optical path directed to the object of observation, receiving electrooptic route, digital calculator and information consumer. With horizontal modulator comprises a transparent electroconductive layer coated on the first dielectric transparent substrate, covered with a transparent gel-like layer, and a system of n pieces of line transparent horizontal electrodes arranged in the same plain on the second dielectric transparent substrate placed with a clearance above the transparent gel-like layer and connected electrically to the control system of the horizontal linear modulator. Vertical linear modulator comprises a transparent electrically conductive layer coated on the first dielectric transparent substrate, covered with a transparent gel-like layer, and a system of m pieces of line transparent electrodes arranged in the same plain on the second dielectric transparent substrate, placed with a clearance above the transparent gel-like layer and connected electrically to the control system of the vertical linear modulator. Moreover, a laser emitter, a horizontal linear modulator control system, a vertical linear modulator control system, the receiving electrooptic route and the information consumer are electrically connected to the digital calculator.

EFFECT: ability to control direction, intensity, frequency and phase characteristics of light radiation.
