More Information
Summary: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.
