The purpose of this research is to generate an early warning system for large mass movements that utilize optical fibers. Optical fibers are preferred due to their suitability in field conditions as well as their continuous and fast data transfer characteristics. The optical fiber system is composed of optical fiber cables and a device called BOTDA. This system measures mass movement in terms of relative strain that changes due to the relocation of the cable. In addition, the system can monitor the effects of the triggering factors that cause mass movements (i.e., hydrological, hydrogeological, seismic effects). The system was deployed in a landslide-prone region in Kocaeli, Turkey and measured the change in strain. This study revealed that the optical fiber system is reliable and well-suited for monitoring of deformation related engineering applications such as mass movements. The system can also adapt successfully to be used as an early warning system with the definition of site-specific threshold strain values and gives an alarm.

An optical fiber radiation sensor for remote detection of radiological materials Klein, DM; Yukihara, EG; Bulur, Enver; Durham, JS; Akselrod, MS; McKeever, SWS (Institute of Electrical and Electronics Engineers (IEEE), 2005-08-01) This paper demonstrates the feasibility of a portable radiation sensor system that uses the pulsed optically stimulated luminescence technique to remotely interrogate an aluminum oxide (Al2O3:C) radiation sensor via an optical fiber. The objective is to develop a system for applications requiring simple and inexpensive sensors for widespread monitoring of ionizing radiation levels, which can be remotely interrogated at regular periods with little or no human intervention and are easy to install, operate, an...
Application of an Optical Fiber Based Monitoring System to a Mass Movement Area Arslan Kelam, Arzu; Akgün, Haluk (2020-06-28) The purpose of this study is to generate a long-term and continuous monitoring system that is near-real-time for mass movements by utilizing optical fibers. The system is composed of fiber optic cables and a device called BOTDA (Brillouin Optical Time Domain Analyzer), which is responsible for sending laser signals to the fiber optic cable and collecting backscattered light. The system measures the distributed strain along an optical fiber cable when mass movement displaces the cable and causes differences ...
Application of an optical fiber-based system for mass movement monitoring Arslan Kelam, Arzu; Akgün, Haluk; KOÇKAR, MUSTAFA KEREM (2022-03-01) This paper assesses the stages and findings of a mass movement monitoring system developed for continuous long-term monitoring applications using optical fiber cable as a sensor to decrease the risks associated with slope instabilities. During this study, a system composed of optical fiber cables and a device referred to as the Brillouin Optical Time Domain Analyzer (BOTDA) has been used. This system has been implemented in a risky landslide area in the Bahcecik region of Kocaeli, one of the active landslid...
A Vibration Based Mechanical IR Detector and an IR Imaging Method Using The Same Azgın, Kıvanç (Dünya Fikri Mülkiyet Teşkilatı, 2013) The invention relates to a vibration based mechanical IR detector having one or more than one resonating pixel structure and an IR imaging method for measuring incoming IR radiation by means of mechanical resonance of the resonating pixels.
A laterally resonating gravimetric sensor with uniform mass sensitivity and high linearity Eroglu, D.; Bayraktar, E.; Külah, Haluk (2011-09-01) In this paper, a laterally resonating gravimetric sensor with high linearity and uniform mass sensitivity is presented for biochemical sensor applications including rare-cell detection. The sensor utilizes symmetrically placed, balanced, folded spring beam structures to ensure lateral motion of the proof mass and limit the displacement difference between the proof mass center and edges. The dynamic mass sensitivity range of the resonator is increased by using the above mentioned properties of the resonators...
