Abstract

With the increasing adoption of LIDAR technology in recent years, the beam scanning system, an integral component of LIDAR, has garnered significant attention. The beam scanning system represents a laser scanning technology capable of achieving rapid, highly precise, and stable performance. However, conventional mechanical beam scanning systems, which are widely used, suffer from large size and susceptibility to wear and tear. Similarly, solid-state beam scanning systems often encounter issues such as limited scanning angles and slow scanning speeds. To address the shortcomings of existing solutions, we propose a novel solid-state beam scanning system based on Metasurface-integrated VCSEL as the laser light source in this paper. By redirecting the outgoing laser light from the Metasurface-integrated VCSELs, we generate a largearea spatial point cloud in space, thereby facilitating beam scanning tasks. Additionally, we validate the efficacy of our proposed system through experimentation using an FPGA demo board to simulate the VCSEL driver chip. This experimental verification successfully demonstrates the real-time dynamic beam scanning capabilities of our proposed scheme.
