Article Experimental Investigation of Refractive Index Measurement of Common Solvents and Aqueous Solutions in the Infrared Wavelengths(Balkan Yayın, 2018) İde, Cansu; Yüksel Aldoğan, Kıvılcım; Yüksel, KıvılcımWe proposed and experimentally demonstrated a fast and simple technique to measure refractive index of liquids. A commercial Optical Time-Domain Reflectometer (OTDR) was implemented for interrogating sensor tips from a remote location. The system uses Fresnel reflected light from standard single mode fiber tips as sensing points without requiring any chemical coating, delicate fiber components, and/or sophisticated architecture at the sensor head. We reported new measurements of refractive indices of common solvents and solutions at both 1550 nm and 1625 nm. The precision of the proposed measurement system was found to be in the order of 10-4. The experimental results have been validated by the way of theoretical calculations.Master Thesis Analysis and Implementation of Optical Fiber Sensors for Process Monitoring of Composite Materials(Izmir Institute of Technology, 2016) Yılmaz, Anıl; Yüksel Aldoğan, Kıvılcım; Yüksel Aldoğan, KıvılcımThe use of composite materials in many industrial applications and structures under high stress (airplane wings, unmanned air vehicles, wind turbines, etc.) has been exponentially growing thanks to their lightweight, superior strength, durability, and corrosion resistance. However, the unique mechanical properties of composite materials cannot be fully exploited without monitoring them when material is placed under constraints. It is essential to monitor their behavior not only in the field but also during manufacturing process to ensure the high quality of manufactured materials. For this purpose, the use of optical fiber sensing, particularly the embedding of fiber Bragg grating (FBG) sensors into composite materials has been gaining growing popularity thanks to various advantages of FBGs. In this context, the main purpose of this thesis is to demonstrate the feasibility of using optical fiber sensors for process monitoring (cure and resin flow) of fiber reinforced thermoset composite materials. The first sensor type studied in the thesis was based on Fresnel reflection. The capability of monitoring the curing profile of liquid matrix (mixture of resin and hardener) has been demonstrated by the way of Fresnel reflection sensor interrogated by Optical Time Domain Reflectometry (OTDR). Then, FBG sensors were embedded into composite plates to measure the temperature change during resin injection and cure cycle, as well as determining the residual strain inside the material. In spite of the popularity of using FBG sensors, most recent researches clearly prove that there is still a lack of technical maturity in real life applications in interrogating embedded FBGs for strain measurements. There is still room for new sensing approaches. In the last part of the thesis, we proposed a novel method to interrogate fiber cavity ring-down (CRD) loop by using OTDR which makes this sensing approach more practical and cheaper than the conventional techniques. Thanks to these advantages, our proposed interrogation method can be implemented for strain measurements inside the composite materials as an alternative to the FBG sensors.Article Frekans Modülasyonlu Sürekli Dalga (fmsd) Ölçüm Sistemlerinde Faz Gürültü Etkisinin Telafisi(Gazi Üniversitesi, 2018) Vardarlı, Eren; Yüksel Aldoğan, Kıvılcım; Aldoğan, Kıvılcım YükselBu makalede, tüm tasarım parametreleri dikkate alınarak, Frekans Modülasyonlu Sürekli Dalga ölçüm sistemlerinde (FMSD) kullanılan faz gürültüsü telafi algoritmalarının analizi sunulmuştur. Bu sayede radyo frekansından optik frekanslara kadar FMSD-tabanlı sistemler için genel ve gerçekçi bir model oluşturulmuştur. Önerilen faz gürültüsü telafi algoritmasının geçerliliği benzetimler aracılığı ile doğrulanmıştır. Benzetim sonuçları makalede sunulan matematiksel modeller ile uyum içerisindedir. Bu çalışma, doğrusal olmayan frekans modülasyonun ortaya çıkardığı pahalı ve karmaşık donanımsal gereksinimlerin üstesinden gelinebilmesini sağlayarak, birden fazla teknolojik alanda (örn. SAR radarlar, fiber optik sensörler) etki yaratabilirArticle Citation - WoS: 3Citation - Scopus: 3Current Sensing Using a Phase-Sensitive Optical Time Domain Reflectometer: Feasibility Study(Elsevier, 2022) Wuilpart, Marc; Şirin, Şamil; Yüksel Aldoğan, KıvılcımA novel method for distributed current sensing using an FBG-assisted Phase-OTDR with Mach-Zehnder Interferometer is proposed. The detrimental effect of the intrinsic linear birefringence of the sensing fiber is solved by calibration. An FBG pair is written at the two ends of the spun fiber coil to eliminate phase fading and increase the measurement accuracy. A simulation tool was developed to reveal the feasibility of the approach by investigating the impact of the detector noise as well as the effects of bending- and FBG-induced linear birefringence on the sensing performance.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.Master Thesis Endüstriyel Isıtma Sistemlerinde Fiber Optik Sensör Uygulaması(2025) Durak, Büşra; Aldoğan, Kıvılcım YükselBu tezde(*), endüstriyel mikrodalga ısıtma sistemlerinde oluşan dengesiz ısı dağılımı problemlerini çözmek ve olası yangınları tespit etmek için fiber optik Bragg (FBG) sensör tabanlı bir izleme sistemi geliştirildi ve değerlendirildi. Proje kapsamında, modifiye edilmiş mikrodalga sisteminde hem laboratuvar tipi fırın testleri hem de kontrollü deneyler gerçekleştirildi. Politetrafloroetilen (PTFE) paketlenmiş ve paketlenmemiş fiber konfigürasyonları sıcaklık kalibrasyonlarında test edildi ve sensörlerin hassasiyet katsayıları elde edildi. Mikrodalga fırın sisteminde uygulanan mermer blok testlerinde, yeni kavite tasarımının ısıyı daha homojen bir şekilde dağıttığı gösterildi. Yangın algılama testlerinde, CuO kaplamalı IR duyarlı FBG sensörlerinin entegrasyonunun test alevlerine hızlı ve seçici bir yanıt verdiği gösterildi. Elde edilen sonuçlar, mikrodalga teknolojilerinde FBG sensörlerinin hem ısıtma sürecini optimize etmek hem de sistem güvenliğini artırmak için etkili ve güvenilir bir çözüm olabileceğini kanıtladı.

Smart monitoring systems should address these issues without interrupting railway operability. Many successful works have been carried out to provide railway monitoring functions using fiber Bragg grating (FBG) sensors on rail. Most of them are based on strain measurement due to the train passage. This paper presents a highly sensitive means for railway monitoring based on vibration measurement. FBG accelerometers placed on sleeper have been employed as sensor heads, which significantly facilitated the field sensor installation work compared to the positioning on the foot of the rail. An optimized signal demodulation algorithm has been effectively used to extract from the accelerometer traces both the axle number and the average speed information. Excellent capability of the developed system to obtain both parameters has been demonstrated by the way of field trials carried out on a Belgian railway line, during its normal operation. Easy installation, multi-function diagnosis, good data integrity, and compatibility with fiber optic sensors make the proposed sensor a good candidate for railway monitoring applications.Article Citation - WoS: 25Novel Monitoring Technique for Passive Optical Networks Based on Optical Frequency Domain Reflectometry and Fiber Bragg Gratings(Institute of Electrical and Electronics Engineers Inc., 2010) Yüksel, Kıvılcım; Wuilpart, Marc; Moeyaert, Véronique; Mégret, PatriceAn efficient monitoring method having a very short measurement time (a few seconds) is proposed.
