Application of voice coil motor in Scanning Mirror of laser radar. With the rapid development of laser radar technology, it has been used in many fields, such as military, aerospace, civil, etc. . 

     The laser radar is generally composed of a transmitting system, a receiving system, information processing, a rotating mechanism, etc. . The transmitting system is a laser in various forms, and when the laser emitted by the laser hits an obstacle, through the reflection of the obstacle, the reflected light will be collected to the receiving system through the Lens Group. As for the signal processing unit, it is responsible for controlling the laser emission and the signal processing received by the receiver, according to these information, the distance information of the target object is calculated, and the above three components constitute the core parts of the measurement. The rotating mechanism is responsible for the above-mentioned core components to rotate at a stable speed, so as to achieve the scanning of the plane, and produce real-time floor plan information. 

    At present, the technology of Lidar has been improved continuously, and the main components are also improving day by day. In the case of the rotating mechanism, it has been replaced by the scanning galvanometer, which will be the laser source of the Lidar, through the swing of the two mirrors on the motor, the laser array is formed, and the laser scanning imaging effect is achieved. Notice that the scanning galvanometer is moved by the two mirrors on the motor, so that the two mirrors are moved by the motor, which has been used to move the voice coil motor. 

     Kunshan developed and produced the TMES voice coil motor (TMER) to bend the TMES series voice coil motor to meet the swing of the angle, this type of motor can provide 120 degrees of swing angle, torque up to 50n. "M. ". The typical applications of the swing voice coil motor are laser mirror reflection technology, rotary valve, damper and so on. Its markets include: Semiconductor Industry, Automation, industry, aerospace industry.
