摘要:
A simple model of the interaction between the optical and thermal properties of the sample is shown to predict signal saturation in photoacoustic spectroscopy in excellent agreement with measurements on a methylene blue dye solution. The measured onset of signal saturation as a function of the absorption is accurately predicted by the model from the sample’s thermal properties. The effect of light reflection by the sample on the photoacoustic signal is discussed.
