Railway and train security are very important in preventing service disruption and ensuring
quality and safe journeys. Conventional gauges are used in laboratory environments for the …

In this study, a Fiber Bragg Grating (FBG) based temperature sensor is designed. Simulation
is conducted to observe FBG's response to the temperature change. The temperature …

Fiber optic cables are widely used in sensor applications of temperature, strain and
pressure. The long sensing range, minimal power consumption and other advantages of …

In the chain and rope hoist systems of large cranes, instant and monitoring of the strain
caused by different loads is of great importance. Strain is a size that cannot be measured …

In this study, Brillouin Gain Spectrum (BGS) is experimentally analyzed in the Brillouin
Optical Time Domain Reflectometry (BOTDR) and Brillouin Optical Time Domain Analyzer …

In this study, a temperature measurement was performed by determining the linear slope in
the transmission spectrum of fiber Bragg grating (FBG) and by designing a temperature …

In this study, the effects of erbium-doped fiber amplifier (EDFA) on Brillouin and Rayleigh
power spectrums are observed. For this analysis, Brillouin Optical Time Domain Analysis …

In railways, to prevent the service failure and provide quality-safe journey, track and train
safety has an important role. Specially broken and buckled rails, deterioration of wheels and …

The Brillouin backscattered wave was examined in a short-length single-mode fiber at
different ambient temperatures using a 1553-nm wavelength laser source. To obtain …

In this study, sensor array is designed with 4 piece of FBGs to measure temperatures using
the broadband laser source. These FBGs are put into thermal medium and temperature is …
