New Vibroscope Transducer
A. E. Stearn · Review of Scientific Instruments · 1966
A transducer system is described which enables the transverse frequency of resonance of strings to be determined with great precision. The theoretical discussion enables the magnitude of the output to be calculated, and a practical system used by the author is given. The excitation and detection of movement of the fiber is purely electrical, depending on the fact that a charged fiber vibrating with a small amplitude between two electrodes causes a charge movement at the electrode proportional to its displacement.
