A new type of fiber-optic pressure sensor based on a specially developed side-hole fiber is presented. It allows for unambiguous and fast phase-shift measurements in the range from -/spl pi//2 to +/spl pi//2 with a sampling rate of 5 kHz and resolution of about 1% of full scale (2 /spl middot/ 10/sup -3/ atm).
