Paper Abstract

The fiber-optic acoustic sensing have been studied 1)-5) by utilizing the pressure-phase shift in laser light going through an optical fiber. We studied 5) previously an ultrasonic sensor using a polarization-maintaining optical fiber (PMF). In this paper, the relation between the pressure-induced phase shift and the laser light transmitted through a PMF is more concisely analyzed. Moreover, the broad range of the linear relation by the phase modulation using a Piezo-Electric Transducer (PZT) is studied.
