20. Distributed strain and temperature sensing over 100??km using tunable-wavelength OTDR based on MEMS filters

Abstract

The possibility of distributed wide-range strain and temperature measurements in a 100 km long optical fiber using tunable-wavelength low-coherence optical time-domain reflectometer (OTDR) is demonstrated. The specified distance range is provided by employing two narrowband microelectromechanical system (MEMS) spectral filters tuned synchronously as well as by taking advantage of Raman amplification and amplification by remotely pumped erbium-doped fiber segments built into the fiber under test. With the time of a single measurement of 10 min and the spatial resolution of about 1 m, the measurement range reached 1000 µ? in strain units, which is equivalent to the temperature range of 110°C.

Abstract

It was found that the content of water-and salt-soluble proteins in egg melange (egg white and yolk mixed in their natural ratio), when dehydrated in the temperature range from 40 to 50C, changes insignificantly, whereas at a temperature of 60C the content is reduced by 20-22% from the initial level. It was also found that the dehydration process is accompained by a decrease in the quantity of protein nitrogen and an increase in the quantity of nonprotein nitrogen. The degree of change in these nitrogen fractions is most clearly expressed at 60C. Taking into account the duration of the process, the optimum temperature for drying the egg melange is 50C.

27. Random jumps in the phase-OTDR response.

Abstract

In the paper, we present a qualitative analysis of the dual-pulse phase optical time domain reflectometry (phase-OTDR) response to uniform and nonuniform propagating fiber strain. It is found that on average over all realizations of scattering centers the response of the dual-pulse phase-OTDR is linear with respect to an external perturbation. Meanwhile, individual responses contain random phase jumps, which are an intrinsic property of phase-OTDR. These jumps are the result of nonlinear responses of the scattering fiber segments and arise due to interference of random backscattered fields varying in time. Two types of phase jumps are considered: π jumps and 2 π jumps; the first type is caused by the fading in phase-OTDR spatial channel, while the second type occurs when a nonuniform perturbation propagates along the fiber. The origin of the phase jumps is explained by considering the simulated response on the complex plane. It is shown that the distribution of 2 π jumps can be well described by the Gaussian probability mass function (PMF), provided the number of 2 π jumps is large. The conducted experiments on the registration of uniform and nonuniform fiber strain confirm the presence of the jumps in the phase-OTDR response.
