Abstract

An acoustic wave detector may include: an exterior housing with an exterior housing wall, a gas chamber located within the exterior housing and configured to receive a gas therein. The exterior housing wall may include an aperture providing a gas passage between the gas chamber and the exterior of the acoustic wave detector. The acoustic wave detector may further include an excitation element configured to selectively excite gas molecules of a specific type in the gas received in the gas chamber in a time-varying fashion, thereby generating acoustic waves in the gas, and an acoustic wave sensor configured to detect the acoustic waves generated in the gas and acoustic waves generated outside of the acoustic wave detector. The acoustic wave sensor may have an acoustic port overlapping with the aperture in the exterior housing wall.
