Acousto-Optic Detection for Photoacoustic Spectroscopy
초록
This paper describes several optical microphones, "optophone", where a low-power He-Ne laser beam is deflected by a reflecting diaphragm mounted on a photoacoustic cell. A comparision of an acousto-optic detection to a conventional microphone shows comparable sensitivities for the photoacoustic detection. The greatest application of these detections may be found where small volume spectro-phone cells are employed, or where conventional microphones cannot be employed because of high or low temperature or chemical corrosion problems. problems.
