Article Citation - WoS: 101Citation - Scopus: 129Scientific Applications of Distributed Acoustic Sensing: State-Of Review and Perspective(MDPI, 2022) Gorshkov, Boris G.; Yüksel, Kıvılcım; Fotiadi, Andrei A.; Wuilpart, Marc; Korobko, Dmitry A.; Zhirnov, Andrey A.; Lobach, Ivan A.This work presents a detailed review of the development of distributed acoustic sensors (DAS) and their newest scientific applications. It covers most areas of human activities, such as the engineering, material, and humanitarian sciences, geophysics, culture, biology, and applied mechanics. It also provides the theoretical basis for most well-known DAS techniques and unveils the features that characterize each particular group of applications. After providing a summary of research achievements, the paper develops an initial perspective of the future work and determines the most promising DAS technologies that should be improved.Article Citation - WoS: 19Citation - Scopus: 21Spectral Shadowing Suppression Technique in Phase-Otdr Sensing Based on Weak Fiber Bragg Grating Array(The Optical Society, 2019) de Miguel Soto, Veronica; Jason, Johan; Kurtoğlu, Deniz; Lopez-Amo, Manuel; Wuilpart, MarcA postprocessing procedure is presented to suppress spectral shadowing in phase-OTDR sensing systems based on a weak fiber Bragg grating array. A complete theoretical analysis of the interfering signals has been carried out to identify a compensation method. The proposed approach has been applied to simulated and experimental phase-OTDR in the context of vibration measurements. Fast Fourier transform has been employed to analyze the obtained results, which has verified the validity of the proposed method to suppress spectral shadowing.

It is capable of measuring IR radiation independently from the environmental temperature fluctuations. Experimental work shows that this IR detection prototype have strong conveniences (fast response and reliability in harsh environment) compared to previous detectors which makes it a very good option for early fire detection systems. © 2011 Elsevier Ltd.

The equal-length branches can be effectively monitored, but also the information of temperature at any place in the network can be obtained. The feasibility of this technique is experimentally demonstrated. © 2010 OSA.Article Citation - WoS: 35Complete Analysis of Multireflection and Spectral-Shadowing Crosstalks in a Quasi-Distributed Fiber Sensor Interrogated by Ofdr(Institute of Electrical and Electronics Engineers Inc., 2012) Yüksel, Kıvılcım; Moeyaert, Véronique; Mégret, Patrice; Wuilpart, MarcWe present the analysis of a quasi-distributed fiber sensor based on the concatenation of identical low-reflective fiber Bragg gratings (FBGs) taking into account both multireflection and spectral-shadowing crosstalks. This allows obtaining more realistic values of the design parameters such as the maximum number of sensing points, the reflectivity of the gratings, and the distance between the sensing points. © 2001-2012 IEEE.
