Abstract: A magnetic ring and a magnetic-ring-based system are provided. The magnetic ring includes an inner magnetic ring including an inner coil and an outer magnetic ring corresponding to the inner magnetic ring and including an outer coil facing the inner coil along a circumference of the outer magnetic ring. The inner magnetic ring is connected with a stationary part in a range-finding system, and the outer magnetic ring is connected with a rotating part in the range-finding system. In response to a rotation of the rotating part with respect to the stationary part, the outer magnetic ring rotates with respect to the inner magnetic ring to generate a magnetic field between the inner coil and the outer coil to perform one of data transmission or power transmission in the range-finding system.

Abstract: The present application discloses a method and device for measuring time of flight and a LiDAR, and belongs to the field of ranging. In the present application, because a shared device of a first transmission link and a second transmission link is a temperature-sensitive device, the delay time of the temperature-sensitive device may be eliminated according to the differential processing of first transmission time and second transmission time. Thus the measurement results of the time of flight are only related to the delay time of the non-temperature sensitive device, thereby reducing the problem of the inaccurate measurement of the time of flight of a target object caused by the temperature change of a device for measuring. Therefore, the accuracy of the measurement of the time of flight of the device for measuring is improved.
