摘要: 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.
