概要
- 論文の詳細を見る
A new spectroscopic measuring scheme, photothermal interference spectroscopy (PIS), has been proposed, analyzed and demonstrated for the first time. A sample under study is set in one of the arms of a Mach-Zehnder interferometer, and its refractive index is modulated by a periodically modulated pump laser beam. A signal dependence on a sample concentration is proportional to the product of the trigonometric function and the Bessel function. Applications of this method to gas monitoring and to gas and liquid chromatographies are also discussed.
