基于超辐射发光二极管的并行抗干扰激光雷达
Parallel anti-interference LiDAR based on super-luminescent diode
摘要
Abstract
As the increasing deployment of multiple LiDAR units within shared environments has intro-duced significant challenges,particularly due to mutual interference among coexisting systems.Such inter-ference can cause substantial disruptions and elevate the risk of accidents,thereby rendering the mitigation of multi-LiDAR interference a critical research focus.This study proposes an innovative LiDAR scheme utilizing a wideband incoherent spontaneous emission noise source generated by a super-luminescent diode(SLD),enabling parallel detection without reliance on complex modulation techniques.Through a filter-ing approach,the system achieves parallel output across multiple uncorrelated modes,which substantially enhances its anti-interference performance.Moreover,the implementation of multi-channel transmission and detection contributes to improved imaging speed.A four-channel parallel anti-interference LiDAR sys-tem was developed based on this concept,incorporating a fiber-optic array and a galvanometer for signal transmission and reception,and capable of three-dimensional imaging at a 0.3 m range.The system suc-cessfully reconstructed a target scene measuring 5 cm×7 cm,achieving a ranging accuracy of 1.6 mm.The system's anti-interference capability was further validated,demonstrating resilience against interfer-ence from analogous LiDAR signals with a signal-to-noise ratio up to 11.2 dB.The findings present a via-ble approach to enhancing the reliability and safety of LiDAR systems operating within complex,multi-de-vice environments.关键词
