Abstract
A LIDAR-type device for a remote spectroscopy of a matter includes an optical emission channel that includes a laser source and an optical waves frequency generator to generate a first comb, a second comb, and a local comb. Each comb includes at least one stripe. A transmit telescope emits an emission signal. A reception channel includes a receive telescope that receives a signal reflected by the matter traversed by the emission signal and a detection system that detects a first beat signal of the at least one stripe of the local comb with the corresponding first stripe of the first reflected comb, a second beat signal of the at least one stripe of the local comb with the corresponding second stripe of the second reflected comb, and a third beat signal of the at least one first beat signal with the at least one second beat signal.
