Abstract

A new type of fiber-optic sensor for measuring fast changes of hydrostatic pressure is presented. The sensor is based on highly birefringent side-hole fiber and employs the low-coherence interferometric scheme to detect phase shifts induced by pressure changes. The decoding system is based on a fringe counting method. The sensor is characterized by a resolution of 1/8 of an interference fringe, counting speed of 5kHz, and a pressure range up to 2. 1 MPa.
