Spectroscopy processing for the NO measurement based on the room-temperature pulsed quantum cascade laser
基于室温脉冲量子级联激光器的NO气体检测中的光谱处理方法研究

The intra-pulse spectroscopy based on room-temperature pulsed quantum cascade(QC) lasers was introduced.With a room-temperature pulsed QC laser centered at 1904 cm-1,the sample NO gas has been detected.The least-squared algorithm of baseline fitting and concentration retrieving method were introduced for the single line spectroscopy detection,and the gas concentration can be calculated with scan integration and the corresponding values from HITRAN04 database by direct-absorption technique,without calibratio...
