Abstract
Disclosed is a remote spectroscopy device of the LIDAR type including a module for generating an emission signal, an emission module for sending the emission signal toward a targeted material, a receiving module for receiving a response signal and a module for postprocessing of the response signal to determine a composition of the targeted material. The generating module includes at least two laser sources, each laser source being able to generate a laser signal at a predetermined wavelength, an upstream mixer able to mix the laser signals generated by the different laser sources, and a first modulator able to modulate the composite signal at a first modulation frequency to form the emission signal.
