Zusammenfassung:	一种光学气体鉴别系统，包括测量单元(20)、已调制光源(10)、麦克风(22)和信号放大器(30)。光源(10)包括多个激光二极管(12)并可以发出具有特定波长的已调制光。气体鉴别系统通过使用信号处理器(70)和具有各种信号模型的数据库(60)可以确定目标信号。 An optical gas identification system including a measuring cell ( 20 ), a modulated light source ( 10 ), a microphone ( 22 ), and a signal amplifier ( 30 ). The light source ( 10 ) comprises a plurality of laser diodes ( 12 ) and can selectively illuminate the modulated light with specific wavelengths. The gas identification system can determine the object signal by use of the signal processor ( 70 ) and the database ( 60 ) with the various signal patterns.
