Construction of Ghost Imaging LiDAR System Based on Dual Fast Mirrors

Influenced by factors such as system bandwidth, rotational inertia, and tracking range in the GI LiDAR system, reliance on a large inertia tracking mechanism alone is challenging. Conversely, a small inertia tracking system may struggle to satisfy the system’s operational range needs. A composite axis control system is formed by combining a large inertia tracking system with a small inertia one to fulfill the tracking accuracy demands. In order to enhance the receiving aperture of the GI LiDAR system, this paper introduces a GI LiDAR system based on dual fast mirrors. Furthermore, a high-precision composite axis PAT control method is introduced to address the motion blur issue with the framework of the dual fast mirrors-based GI LiDAR system.
