Abstract

The high spectral lidar principled sample machine that can obtain the target spectral information as well as the twodimensional images was developed from the perspective of motoring the marine oil spill pollution in this thesis, this high spectral lidar principled sample machine can cover the wavelength range from 400nm to 1100nm. And this high spectral lidar principled sample machine was applied for the remote sensing detection of vegetation, oceans, minerals and some other ground object targets, through measuring the spectral radiance of the hyperspectral laser interacting with the target and returning to the lidar receiving system, so as to realize the real-time monitoring of vegetation, oceans and minerals. For the purpose of realizing the quantitative observation, an accurate radiometric calibration on high spectral lidar was required. The radiometric calibration of high spectral lidar was aimed at its receiving system, that was to determine the responsivity of the principled sample machine to the target spectral radiance. After finishing debugging, all the indicators of the principled sample machine can meet the application requirements, which provided a new monitoring means for the marine oil spill in our country and was of great significance for the future protection of marine environment and the application and exploitation of marine resources.
