APPLICATION OF PHOTOACOUSTIC SPECTROSCOPY FOR GAS ANALYSIS AND MEASUREMENT
Abstract
This paper presents photoacoustic effect alongside with its history and theoretical background. Two methods of photoacoustics are explained: photoacoustic spectroscopy and photoacoustic imaging. Pratcical part of this paper considers measuring CO2 concentration in a room in different conditions using CO2 3 Click board which is based on photoacoustic spectroscopy.
