Access control lidar manufacturers said that lidar mainly includes a laser emission part, a scanning system, a laser receiving part and an information processing part, and the structure is relatively complex.

From the perspective of lidar work, access control lidar manufacturers can divide it into four major parts:
1) Laser emission part: the excitation source periodically drives the laser, emits laser pulses, the laser modulator controls the direction and number of lines of the emitted laser through the beam controller, and finally emits the laser to the target object through the emission optical system;
2) Laser receiving system: The access control lidar manufacturer stated that through the receiving optical system, the photoelectric detector receives the laser reflected from the target object and generates a receiving signal;
3) The scanning system rotates at a stable speed to scan the plane and generate real-time plan information;
4) Information processing system: The received signal undergoes amplification processing and digital-to-analog conversion, and is calculated by the information processing module to obtain the target surface morphology, physical properties and other characteristics, and finally establish an object model.
Access control lidar manufacturers said that the complexity of lidar itself and the high price of core components determine the short-term price of lidar, especially the short-term price of mechanical lidar.
Access control lidar manufacturers said that there are many lidar components, and the different technical choices of each component will result in different effects and costs, which also brings the diversity of lidar technology routes. The access control lidar manufacturer said that the discovery lidar can be divided into 5 core technologies from ranging method, emission method, beam operation method, detection method and data processing method. Each core technology has different technical branches, effect, cost, The current difficulty of mass production is different, and the selection of different branch technologies in the five core technologies has also led to different laser radar technology routes.
