Infrared laser radar for practical airborne natural gas pipeline inspection
实用化机载天然气管道泄漏监测红外激光雷达

The problem of natural gas pipeline leak becomes increasingly serious. A practical airborne natural gas pipeline inspection laser radar which is based on tunable diode laser spectroscopy was developed. The operating principle of this instrument was introduced, the system configuration and method of design were discussed. The key technologies including high-accuracy laser frequency stabilization and real time calibration were further discussed. The analysis results of ground and airborne test proved that the instrument can be applied in practical project.
