Paper Abstract

We use dynamic scanning laser detection methods to improve the traditional static gaze, and propose a new type of laser proximity detection method based on optical circumferential scanning technology. We optimize the optical structure of laser proximity detection system and design a set of multi-level optical focusing plastic lens. The simulation results show that compared with the traditional single-stage focusing lens, the brightness of center irradiation is enhanced by nearly 10 times. The experimental results show that the system can effectively realize proximity 360° circumferential detection, increase the echo energy of pulsed laser and enhance the detection range.
