I. What is LiDAR
LIDAR is a technological system that uses a combination of lasers, GPS and inertial measurement units to acquire data and generate highly accurate digital elevation models (DEMs). It is able to accurately measure the position of a light beam hitting a target object and achieve centimeter-level distance measurement accuracy. The biggest advantage of LiDAR is its accuracy and efficient operation ability, which can quickly collect a large amount of data and provide accurate and reliable measurement results for various applications.
2. LiDAR industry prospects
LiDAR, as a core device at the perception level of autonomous driving, has the great advantage of accurate, fast and efficient operation. Compared with other sensors such as camera and millimeter wave radar, LiDAR has become one of the key sensors to realize autonomous driving above L3 level. The multi-sensor fusion solution has lower technical barriers and better imaging quality than the pure vision route, and is becoming the mainstream path for autonomous driving and advanced assisted driving. Domestic automotive-grade LiDAR standards are gradually improving, and the continuous innovation of semi-solid-state and solid-state technologies further enhances the development potential of LiDAR as a core configuration for autonomous driving.

3. The classification of LiDAR
The overall rotation of the transceiver array is driven by the motor to realize the scanning of the horizontal 360° field of view range of the space. The distance measurement capability is consistent within the horizontal 360° field of view.
Semi-solid-state solutions are characterized by the decoupling of the transceiver unit from the scanning components, and the transceiver unit (e.g., laser, detector) is no longer subjected to mechanical movement, specifically including the micro-oscillator solution, rotating mirror solution, etc.. Applicable to achieve part of the field of view angle (e.g., forward) detection, the volume is more compact compared to the mechanical rotating radar.
Solid-state solutions are characterized by the fact that they no longer contain any mechanical moving parts, including Optical Phased Array (OPA) solutions, Flash solutions, electronic scanning solutions and so on. They are suitable for detecting part of the field of view (e.g. forward) and are the most compact compared to other architectures because they do not contain mechanical scanning components.

4. LEILI LIDAR motor program.
At present, Leili has two major types of LIDAR motor programs: vibrating mirror and rotating mirror, which can be equipped with two sets of optical encoding and this encoding acquisition system, and can be applied to application scenarios ranging from 300rpm to 10,000rpm. Through the cooperation with the head unicorn enterprises, it has passed the severe environment test of many OEMs and is ranked the first in the world in terms of shipment in the application of high-speed scenarios.
In 2024 rotary mirror and vibrating mirror type motors will account for more than 50% share of the automotive LiDAR industry, and in 2025, we will realize the large-scale mass production of multiple flexible production lines and can meet the demand for multi-species and small batch customization, and continue to provide our customers with products and services with lower cost and higher optical and mechanical reliability.
Leili Motor provides specialized and customized solutions to help customers upgrade their products. For more information, please contact us by mail: marketing@leiligroup.com.
