    Infrared Radiation Detector Interrogated by Optical Frequency-Domain Reflectometer
    (Elsevier Ltd., 2012) Yüksel, Kıvılcım; Caucheteur, Christophe; Renoirt, Jean-Michel; Debliquy, Marc; Mégret, Patrice; Wuilpart, Marc
    We experimentally demonstrated a fast infrared (IR) radiation sensor. 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.

    A Quasi-Distributed Temperature Sensor Interrogated by Optical Frequency-Domain Reflectometer
    (IOP Publishing Ltd., 2011) Yüksel, Kıvılcım; Mégret, Patrice; Wuilpart, Marc
    This paper presents the analysis of a quasi-distributed sensor based on the concatenation of identical low-reflective fiber Bragg gratings. We experimentally demonstrated a temperature sensor using ten cascaded gratings which are interrogated by an optical frequency domain reflectometer. Repeatability measurements highlighted a standard deviation on the measured temperature smaller than 1.5 °C. A complete demonstration of mathematical formulas which are used to obtain the temperature information is also provided. © 2011 IOP Publishing Ltd.

    Complete 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, Marc
    We 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.
