  • Photoacoustic detector with long term drift compensation
    Patent number: 8939006
    Abstract: A photoacoustic detector wherein control circuits compensate for long term variations of components therein including a light source and sensing microphones. The control circuits intermittently energize the source to evaluate changes in at least source resistance. The control circuits intermittently energize an acoustic generator to evaluate changes in one or more generator responsive microphones.

  • Apparatus and method of photoacoustic sensor signal acquisition
    Patent number: 8689607
    Abstract: A photoacoustic detector includes first and second microphones carried by an acoustic sensing chamber. Signals from the microphones are processed using lock-in detection to increase the signal-to-noise ratio. An acoustic pressure generator can be incorporated to calibrate the microphones.
