펄스 레이저 기반 담수용 미세 플라스틱 실시간 센서 모니터링 시스템 연구 = Study on Real Time Sensor Monitoring Systems Based on Pulsed Laser for Microplastic Detection in Tap Water

다국어 초록 (Multilingual Abstract)

Pulsed laser-based optical sensor monitoring systems for real time microplastic particle counting are proposed and developed in this study. To develop our real time monitoring system, we used a 450 nm pulsed laser and a photomultiplier with very high quantum efficiency. First, we demonstrated that the microplastic particle counting system could detect standard micro bead samples of 100, 250, and500 µm in river water. We then performed research concerning pulsed laser-based optical spectral sensor systems for real time microplastic monitoring. Additionally, we demonstrated that the real time microplastic remote monitoring system using LoRa communications could detect microplastic in the tap water resource protection area.
