According to one embodiment, an optical deflection element includes a substrate and three or more electrodes. The substrate has an incidence plane which the laser light enters and an emission plane from which the laser light exits. The three or more electrodes are arranged on the substrate at first intervals in a first direction. Electrodes allow a surface acoustic wave having a first wavelength to be generated in the substrate by applying a voltage thereto. Wiring is provided such that a voltage is selectively applied to the electrodes at an interval between at least two electrodes. The electrodes allow a surface acoustic wave having a second wavelength to be generated in the substrate by applying a voltage selectively at second intervals.

There is provided a simultaneous localization and mapping (SLAM) system including a first LiDAR and a second LiDAR mounted on a vehicle bumper; a LiDAR data merge unit receiving data from the first LiDAR and the second LiDAR, aligning LiDAR times through time synchronization, and then converting the data into a point cloud type and merging the data; an electronic control unit (ECU) providing inertial data of the vehicle for correcting the data merged in the LiDAR data merge unit; and an SLAM unit correcting the data merged in the LiDAR data merge unit by using the inertial data of the vehicle received from the ECU to obtain LiDAR odometry for estimating a movement of the vehicle, generating a 3D map of a road on which the vehicle travels, and extracting a location and a traveling route of the vehicle inside a road.

A sensor comprising a light emitter and light detector coupled directly with or formed directly on a lead frame and directly covered and encapsulated by a layer of light transmissive compound. A gap in the light transmissive compound between the light emitter and the light detector wherein in some embodiments the gap can be filled with a light blocking barrier material.

The laser distance measuring device includes: a laser light emission unit for emitting laser light; a scanning mechanism for scanning the laser light by changing an output angle thereof; a light receiving unit for receiving reflected light of the laser light from an object, to thereby output a light reception signal; a light-detector control circuit for causing the light receiving unit to output the reception signal after setting a light receiving sensitivity for the reflected light at the time when the output angle is small, higher than a light receiving sensitivity for the reflected light at the time when the output angle is large; and a distance calculation unit for calculating, based on the reception signal, a distance to the object. This enhances the distance measuring capability in both cases of measuring a short distance and a long distance.

Implementations described and claimed herein provide a mechanically-scanning 3-dimensional light detection and ranging (3D LiDAR) system including a galvo mirror assembly, wherein the galvo mirror assembly includes a mirror attached to an armature of a galvanometer to reflect a light signal generated by a light generator and received from a target, at least one permanent magnet, and at least one coil configured to carry a current to move the armature.

An optical probe includes an optical housing, a transmitting lens and a receiving lens. The optical housing extends from a proximate end to an opposing distal end. The transmitting lens is disposed at the distal end and is configured to output a first transmitted signal beams having a first transmission axis and a second transmitted beam having a second transmission axis that is different from the first transmission axis. The receiving lens is disposed at the distal end and configured to receive the first and second reflected signal beams corresponding respectively to the first and second transmitted signal beams. The optical housing has formed therein a transmitting optical channel configured to communicate an input optical signal from the proximate end to the transmitting lens. A receiving optical channel separated from the transmitting optical channel communicates the first and second reflected signal beams to the proximate end.
