摘要：

A novel variation in optical correlation spectroscopy is presented. A semiconductor optical amplifier (SOA) is employed as the fight source and an optical fibre delay line is used to achieve the 180 degrees phase shift between the reference and measurement signals. The system was tested-using acetylene (C2H2) gas. Absorption data from the HITRAN database is used to model the theoretical response of the system. Experimental results for the detection of various acetylene gas concentrations have been obtained and compared with theory.
