What is single axis galvo scanners for LiDAR production?

Single-axis galvo scanners are key components used in LiDAR (Light Detection and Ranging) systems for various applications, including autonomous vehicles, 3D mapping, and remote sensing. These scanners play a crucial role in steering the laser beam and enabling rapid and precise scanning of the surrounding environment.

Here is a description of single-axis galvo scanners and their role in LiDAR production:

1. Principle of Operation: Single-axis galvo scanners operate based on the principle of electromagnetic deflection. They consist of a galvanometer mirror, which is a small, lightweight mirror attached to a highly sensitive galvanometer. The galvanometer is an electromechanical device that uses a coil and magnet system to produce angular movement.
2. Mirror and Galvanometer Assembly: The galvanometer mirror is mounted on the galvanometer shaft, which can rotate along a single axis. This axis of rotation determines the scanning plane of the LiDAR system. The mirror is typically made of a lightweight material with high reflectivity, such as aluminum coated with a protective layer.
3. Laser Beam Steering: The galvo scanner, when controlled by the LiDAR system, adjusts the angular position of the mirror rapidly and accurately. This movement redirects the laser beam emitted from the LiDAR transmitter, enabling it to scan the environment within a specific field of view (FOV). The laser beam reflects off the mirror and scans across the desired area.
4. Scanning Range and Speed: Single-axis galvo scanners can achieve high scanning speeds, allowing for rapid data acquisition in LiDAR applications. The scanning range depends on the mechanical design and specifications of the galvanometer, such as the angular range of the mirror and the maximum rotational speed of the galvanometer. The scanning range can typically cover several degrees, providing a wide FOV.
5. Control and Synchronization: The galvo scanner is controlled by the LiDAR system’s electronics and software. The control system sends precise electrical signals to the galvanometer, controlling its movement and allowing for precise scanning patterns. The galvo scanner must be synchronized with other components of the LiDAR system, such as the laser transmitter and the sensor or detector, to ensure accurate data collection.
6. Accuracy and Precision: Single-axis galvo scanners are designed to provide high accuracy and precision in LiDAR applications. The performance of the galvo scanner directly affects the quality and resolution of the generated LiDAR point cloud data. Factors such as mirror stability, galvanometer dynamics, and control system accuracy contribute to the overall performance of the scanner.
7. Compact and Lightweight Design: Galvo scanners are often designed to be compact and lightweight to facilitate integration into LiDAR systems, especially in applications where size and weight constraints are critical, such as autonomous vehicles. The compact design allows for easier mounting and installation in various LiDAR configurations.

In summary, single-axis galvo scanners are essential components in LiDAR production, enabling precise laser beam steering and rapid scanning of the environment. They offer high accuracy, fast scanning speeds, and compact designs, making them suitable for a wide range of LiDAR applications.
