A multiplexed CW Brillouin system for precise interrogation of a sensor array made from short discrete sections of optical fibre
نویسندگان
چکیده
A novel configuration for precise temperature sensing in an array of optical fibre sections is reported. The sections are chosen to have different Brillouin shifts, to enable separation of scattered light signals in the frequency domain, rather than the traditional time domain, allowing lower-noise CW operation and greater precision due to the 100% duty cycle.

Bragg Gratings Interrogation System using MEMS and optical circuits
It is well documented that optical sensors offer many advantages over conventional electronic devices for some applications because they are more versatile, lighter, smaller, immune to electrical interference and can be densely multiplexed. However, to date, many optical sensor instrument systems have been insufficiently robust for use in harsh environments and relatively expensive due to the u...
متن کاملTime-division-multiplexed interrogation of fibre Bragg grating sensors using laser diodes
An intensity-based technique for the interrogation of fibre Bragg grating sensors is described. The technique utilizes two longitudinal modes of a single, pulsed laser diode as a dual-wavelength source for grating illumination. Time-division-multiplexed addressing of sensor arrays in serial and tree topologies is also demonstrated.

An integrated sensor system is presented which displays passive long range operation to 100 km at pico-strain (pepsilon) sensitivity to low frequencies (4 Hz) in wavelength division multiplexed operation with negligible cross-talk (better than -75 dB). This has been achieved by pre-stabilizing and multiplexing all interrogation lasers for the sensor array to a single optical frequency reference...
متن کاملTheoretical study of Stimulated Brillouin Scattering (SBS) in polymer optical fibres
We present the modelling of stimulated Brillouin scattering (SBS) in graded index polymer fibres made with fluoropolymer CYTOPr(Cyclic Transparent Optical Polymer). Comparison of SBS in silica and polymer optical fibres is presented. What emerges is that polymer-based fibre sensors require, compared to silica-fibres sensors, higher power sources (in the order of Watts). The innovative aspect of...

We propose and demonstrate the use of spatial multiplexing as a means to reduce the costs of distributed sensing networks. We propose a new scheme in which remote power-by-light switching is deployed to scan multiple branches of a distributed sensing network based on Brillouin Optical Time Domain Analysis (BOTDA) sensors. A proof-of-concept system is assembled with two 5-km sensor fiber branche...
