  • Publication number: 20240210528
    Abstract: A receiving optical system includes a receiving lens group and a detection module. The receiving module is configured to receive an echo signal obtained by reflecting signal light by a target in a detection region, and a horizontal focal plane and a vertical focal plane of the echo signal are separated. The detection module is configured to perform optical-electrical conversion on the echo signal in order to obtain an electrical signal used to determine association information (such as a distance, a speed, or a grayscale) of the target.

  • Publication number: 20200381612
    Abstract: A non-contact force type micro-rotating mechanism driven by attractive/repulsive force and a manufacturing method thereof, belongs to the field of intelligent micro devices, and mainly relates to micro electromechanical system technology, precision machining technology, precision assembly and the like. The mechanism adopts the interaction force between magnetic poles to replace the connection mode of a traditional through-hole bearing pressure spring positioning shaft, so that the component part structure of the mechanism can be optimized, and the space utilization rate can be greatly improved. Moreover, the attractive force type structure also has the effect of weakening the radial vibration of the motor, and the coaxiality of the rotor and the stator is improved in the running process of the motor. Meanwhile, the rotating mechanism does not directly output shaft work, a structure can be added on the disc-shaped rotor to realize different functions, an actuator and a control object are integrated.
