A newly developed hyperspectral Raman imaging lidar system offers a promising solution for identifying and monitoring plastic pollution in the ocean. This innovative technology can detect and differentiate various types of plastics from a distance, potentially revolutionizing cleanup and prevention efforts.
New technology could remotely identify various types of plastics, offering a valuable tool for future monitoring and analysis of oceanic plastic pollution. A new hyperspectral Raman imaging lidar system can remotely detect and identify various types of plastics, which could help address the critical issue of plastic pollution in the ocean by providing better tools for monitoring and analysis.
Researchers have developed a new hyperspectral Raman imaging lidar system that can remotely detect and identify various types of plastics. This technology could help address the critical issue of plastic pollution in the ocean by providing better tools for monitoring and analysis. 'Plastic pollution poses a serious threat to marine ecosystems and human livelihoods, affecting industries like fisheries, tourism and shipping,' said research team leader Toshihiro Somekawa from the Institute for Laser Technology in Japan.'To manage and protect the marine environment, it's essential to assess the size, concentration and distribution of plastic debris, but traditional lab-based methods are often time-consuming, labor-intensive and expensive.', the researchers describe their new system, which is compact and optimized for low energy consumption, making it suitable for use aboard a drone. They show that the system can identify plastics that are 6 meters away with a relatively wide field of view of 1 mm x 150 mm. 'A drone equipped with our lidar sensor could be used to assess marine plastic debris on land or in the sea, paving the way for more targeted cleanup and prevention efforts,' said Somekawa.'The system could also be used for other monitoring applications, such as detecting hazardous gas leaks.'The researchers previously demonstrated a monitoring system based on a flash Raman lidar technique in which bandpass filters were matched to each measurement target for detection in a successive manne
