LASER SYSTEMS IN MARINE GEOPHYSICS STUDY: AN IMPORTANT TECHNOLOGY IN BRAZIL

The goal of the work is a detailed study about applications laser Systems in Marine Geophysics and a development furthermore debates. It is part of a great work in Marine Enviroment Laser applications, in which the research of the botton sea coast and other applications in the study of bioligical substances had notability, with distinction on a type of laser Systems be named LIDAR (light Ranging and Detection). Was discussed in this work Laser: basis principles (types and actual evolution); Laser Properties (ray light, monocromaticity, time coerence. space coerence, directionality and brilhance); Lidar systems (main systems, advantages and disadventages); the up-date evolution of laser systems in Spaca Shuttle Lidar and the future of Lidars in Brazil.
