摘要

最近的研究(1,2,3)表明，利用干涉测量和傅立叶变换技术，光声光谱(P.A.S.)的光谱范围可以扩展到包括中红外(2.5-25 μm)，以提高信号恢复。这些技术弥补了该地区低强度的源，这使得传统的色散P.A.S.难以执行。

Some Observations on Signal Production in Photoacoustic Fourier Transform Infrared Spectroscopy

Recent investigations (1,2,3) have shown that the spectral range of Photoacoustic Spectroscopy (P.A.S.) can be extended to include the Mid Infrared (2.5-25 μm) by utilising Interferometry and Fourier Transform techniques to improve signal recovery. These techniques have compensated for the low intensity level of sources in this region which has made conventional, dispersive P.A.S. difficult to perform.
