Abstract

A hyperspectral lidar system (HSL) dedicated to underwater detection is studied. Using a white light laser combined with a tunable filter as a light source, the integrated detection of ranging information and spectral information of underwater targets is realized. The system has the echo detection capability of 160 channels in 450nm-610nm wavelength, and the spectral resolution is 10nm. Substance differentiation was achieved by testing different underwater targets, including sponges, ferromanganese crusts, titanomagnetite, and apatite. The underwater application of hyperspectral lidar is initially explored.
