Optical microphone for photoacoustic spectroscopy

open access: yesJournal of Applied Physics, 1988
An optical microphone configuration is experimentally demonstrated. It is based on the deflection of a He-Ne laser beam from a thin reflective pellicle bound on one edge over the duct of a conventional photoacoustic cell. Possible applications of this kind of photoacoustic detection are discussed.
