| Outline of Final Research Achievements |
The effective use of the vast sea area is crucial for Japan as a maritime country, but there is a need to monitor the environmental change parallel to the seabed development. Lidar (light detection and ranging) is a very promising technique for monitoring the vast seafloor. Lidar enables real-time three-dimensional (3D) imaging to measure the round-trip time between pulse emission and laser-induced signal detection and can monitor not only the target distance but also the target identification using the light-matter interaction such as Raman scattering. Therefore, we proposed Raman lidar using a green laser with relatively high transmission in water and demonstrated the remote detection method of oils in water by laser Raman spectroscopy and lidar system.
