Paper Abstract

In this paper a new technique of objects measurement based on multi-wavelength lidar system has been proposed and developed to make horizontal-path laser measurements of objects. The two or more wavelengths laser transmitter operates within and adjacent to the sensitive bands exhibited by the characteristics of each object, the result could be used to establish inversion models of the laser transmitting backscatter signals. The application value and the key techniques of the spectral lidar are analyzed. The lidar wavelength selection method is studied and a hyperspectral experiment had been down to testify the feasibility of the theory. Also issues to approach the final goal of this new technique are discussed.
