Abstract: With the advantages of high resolution, high sensitivity, wide spectral coverage and rapid measurement, the dual-comb spectroscopy technology has developed rapidly in the field of molecular and atomic spectroscopy. First, the basic principle of the dual-comb spectrum measurement technology is briefly introduced, and then a corresponding dual-comb spectrum measurement device is established according to the existing conditions of the laboratory, and the feasibility of the acetylene gas is verified.
Key Words: dual-comb spectroscopy; laser spectroscopy; spectroscopy; optical frequency comb; dual-comb system
