LiDAR for Continuous Remote Monitoring of Air Pollution

Technology Overview

• A technology that uses LiDAR sensors to continuously monitor air pollution remotely by measuring the precise location and concentration of fine particulate matter emitted into the atmosphere, even in distant target areas

• Designed to meet the requirements for LiDAR sensor miniaturization, visual safety, system protection, and high resolution, enabling stable operation in a variety of outdoor environments

Key Technology Features

Core Features for Developing an Optimal Fine Particulate Matter LiDAR

• High-resolution, multi-wavelength scanning LiDAR; the measurement unit and control unit are separated for ease of installation and mobility, and the measurement unit head—which houses the optical system—weighs approximately 25 kg

• Uses an Nd:YAG laser to simultaneously measure ultraviolet, visible, and infrared wavelengths (355 nm, 532 nm, 1064 nm), and incorporates measures to ensure visual safety

• With a range resolution of approximately 2 meters and an angular resolution of < 0.05°, the system enables the remote generation of high-resolution fine dust emission maps

Competitive Advantages of the Technology

Experimental and Demonstration Data

• Production of fine particulate matter emission maps for various areas, including industrial complexes, large-scale facilities, and ports
