Abstract

An alternative to the electrical microphone for photoacoustical detection of trace gases is presented. This microphone is made of a monomode optical fiber wound and glued on a thin plate. This fiber is one arm of a Michelson interferometer. A Sagnac interferometer has also been used and has given better results.
