“…However, the requirement of two separate light sources of a broadband light source and a Raman pump could be a limiting factor for practical implementation of such systems due to the corresponding higher system cost. Recently, P.-C. Peng et al proposed an advanced concept of the use of the linear cavity Raman laser configuration based on a FBG and fiber loop mirror for a long-distance strain sensing system [4] to obtain advantages such as high resolution and high optical signal-to-noise ratio (SNR) and our group also demonstrated a simple, all-FBG based long-distance Raman laser temperature sensing system [5]. Although the use of Raman laser configuration eliminates the requirement of an additional broadband light source and improves significantly the sensing signal quality, it would be very hard to achieve the simultaneous measurement of temperature and strain using the previous system configurations.…”

A novel, Raman amplifier-based long-distance sensing system using a combined sensing probe of an erbium-doped fiber (EDF) and a fiber Bragg grating is proposed for simultaneous measurement of temperature and strain. By recycling residual Raman pump power for generation of amplified spontaneous emission in the EDF after distributed Raman amplification in the transmission fiber, the overall system configuration was significantly simplified without requiring any additional broadband light source. A remote sensing operation of simultaneous temperature and strain measurement is obtained at a location of 50 km. High quality of sensing signals with a ~ 11 dB signal-to-noise ratio (SNR) is readily achieved even after the 50 km transmission with distributed Raman amplification.

In this paper, the results of the long-term temperature monitoring of the compact muon solenoid experiment (CMS) at CERN are shown. The measurements were carried out by means of a system based on fiber Bragg grating (FBG) sensors in wavelength-division multiplexing (WDM). Due to the harsh working conditions at the CMS, the FBG sensor represents the ideal candidate to realize a reliable and accurate sensing system. The sensing principles of the FBG sensor and its temperature characteristics are introduced. A temperature monitoring system based on FBG for high-energy physics applications is designed and installed. The sensing system was used successfully last year in monitoring the temperature of CMS bulkhead. The reported results show good reliability and high accuracy of the FBG sensing system during the long-time working stage.Index Terms-Compact muon solenoid (CMS), fiber Bragg grating (FBG) sensor, high energy physics, monitoring system, temperature.

“…Murphy et al [8] have reported a silica fiber extrinsic Fabry-Pérot (FP) strain sensor to measure temperatures up to 975 • C. Alavie et al [9] have reported a serial multiplexed sensor system where each laser cavity was formed using an FBG and a broadband mirror, measuring the temperature from 20 • C to 160 • C. Kaddu et al [10] have reported multiplexed optical fiber FP sensor systems to measure temperature and strain over the ranges from 20 • C to 70 • C and from 0 to 400 µε, respectively. Peng et al [11] have reported an FBGbased temperature sensor system using a fiber laser to measure temperature over the range from 0 to 40 • C. A Raman fiber laser probe has also been developed [12] for long-distance remote temperature sensing applications, typically reported for use over the temperature range from 30 to 100 • C. Recently, fiber laser-based sensor systems have been developed to measure temperatures up to 500 • C in a single cavity configuration using a chirped FBG (CFBG) and a normal FBG in [13] and [14]. Additionally, some of the commercial manufacturing technologies are also available for temperature measurement applications [15], [16].…”

A parallel multiplexed temperature sensor scheme using a Bragg grating-based fiber laser approach has been developed and evaluated. Multiple laser cavities were formed as the active gain media of the system using a common broadband chirped fiber Bragg grating (CFBG) and several normal FBGs, which were used as optical feedback elements, in conjunction with different lengths of erbium-doped fibers (EDFs). These gain media were externally pumped by light from a 1480-nm laser diode (LD) through a 1480-nm 1 × 4 splitter. Normal FBGs were used as the wavelength-selective and sensing elements of the laser system. Simultaneous laser action at three different wavelengths corresponding to channels 1, 3, and 4, respectively, was obtained using this scheme. The temperature was measured over the range from room temperature (27 • C) to a maximum of 540 • C, which shows the potential of the scheme for quasi-distributed sensor applications.Index Terms-Chirped fiber Bragg grating (CFBG), erbiumdoped fiber (EDF), fiber Bragg gratings (FBGs), fiber laser temperature sensor, multiplexed sensor interrogation.
