چکیده
Abstract In this paper, a distributed esophageal pressure measurement sensor is proposed. Optical frequency domain reflection (OFDR) technology adopted to measure the axial strain change of optical fiber. By designing sensitizing structure, sensing performance can be well improved. The analysis based on finite element simulation carried out and its feasibility verified. Compared with solid high-resolution manometry system widely used at stage, proposed low cost simple in structure. sensitivity reach 65.920μɛ/kPa.

Fiber-Optic Pressure Sensor Based on π-Phase- Shifted Fiber Bragg Grating on Side-Hole Fiber
We present a fiber-optic pressure sensor based on a π-phase-shifted fiber Bragg grating (πFBG) fabricated on a sidehole fiber. Due to the resonance effect of a πFBG, its reflection spectrum features two notches that are dramatically narrower than the linewidth of a regular FBG of similar length. The narrow spectral notches allow high-resolution measurement of their spectral separation, signific...
متن کاملCompact Tb doped fiber optic current sensor with high sensitivity.
A highly sensitive fiber optic current sensor using terbium doped fiber is presented. The Verdet constant of the terbium doped fiber at 1300nm is found to be 19.5μrad/A using both a polarimetric and interferometric type sensor. Measurements on a Sagnac-loop sensor using 10cm of terbium doped fiber placed inside a solenoid show over 40dB of open loop dynamic range as well as a minimum detectable...

متن کاملHigh-sensitivity fiber-tip pressure sensor with graphene diaphragm.
A miniature fiber-tip pressure sensor was built by using an extremely thin graphene film as the diaphragm. The graphene also acts as a light reflector, which, in conjunction with the reflection at the fiber end-air interface, forms a low finesse Fabry-Perot interferometer. The graphene based sensor demonstrated pressure sensitivity over 39.4 nm/kPa with a diaphragm diameter of 25 μm. The use of...
متن کاملFiber optic pressure sensor based on polarization-maintaining photonic crystal fiber for downhole application
We experimentally demonstrate a high pressure sensor based on a polarization-maintaining photonic crystal fiber (PMPCF) with Sagnac loop configuration for downhole application. The pressure sensitivity of the proposed sensor is 4.21 nm/MPa and 3.27 nm/MPa at ~1320 nm and ~1550 nm respectively. High pressure measurement up to 20 MPa has been achieved in our experiment. The sensor also shows redu...
