摘要:
Optical beam deflection is a simple and reliable method for the detection of small displacements. This paper describes its application to the measurement of the displacement of the membrane of a condenser microphone, where the displacement is induced by supplying an alternate voltage to the transducer terminals. A sensitive reconstruction of the dynamic deformation of a microphone membrane in a wide frequency range is obtained. ©1995 American Institute of Physics.
