A study of oceanographic laser sensing using fluorescence and polarization

点击翻译按钮获取中文摘要

This is a feasibility study for developing for measuring underwater particulates and bio-group using a lidar techniques in which polarization and fluorescence are applied. For this purpose, we have investigated polarized diffusion images scattered by particulates and presumed scattering images by a simulation. Also data of laser induced fluorescence of fishes were obtained. Then we have developed a polarized imaging system using the pulse laser, and estimated its SNR in underwater conditions.
