A spectrophone with low resonant frequency compatible with the repetition frequency of a pulsed discharge CO laser is described.
The spectrophone is used for humidity detection in hydrogen and air. The simple and inexpensive system provides a detection
capacity of 10–100ppb/
. The responsivity of the resonant spectrophone is interpreted taking the dependence of the acoustical quality factor on the
geometry into account. 相似文献
