Highly Sensitive Trace-Gas Sensing Method Based on Laser Spectroscopic Sensing of Anomalous Molecular/Atomic Dispersion

Princeton Docket # 10-2584-1 Researchers from Princeton University and the STFC Rutherford Appleton Laboratory (UK) have developed a novel method of high sensitivity molecular detection based on detection of refractive index changes around the absorption line. This method employs heterodyne interferometric measurement with a frequency...
