Shipboard Visibility Measurement System Definition Study

摘要

A study has been performed to define the required characteristics of a shipboard Light-Detection-and Ranging (LIDAR) system to be used for shipboard aerosol extinction measurements at visible and infrared wavelengths. The study is based on an evaluation of several elements including a characterization of maritime aerosol scattering and extinction, an evaluation of various LIDAR system configurations and the practical considerations involved in the use of a shipboard LIDAR measurement system. Performance of an existing hand-held LIDAR system and a suggested upgraded version of this system have been performed and compared. Eye safety considerations and system operating parameters including laser source pulse energy and operating wavelength as well as optical system size have been considered. Recommendations for the development and use of a prototype shipboard LIDAR system have been developed and are included. (Author)
