Fiber-optic temperature sensor based on internally generated thermal radiation
Applied Optics, 1981This paper presents a theoretical and experimental study of a method of sensing temperature with optical fibers with the radiation thermally generated within the fiber. Using quartz fibers it is possible to read temperatures in the range from room temperature to over 1000 degrees C.

Characterization of fiber optic Cerenkov radiation sensor for detecting neutrons
SPIE Proceedings, 2013Cerenkov radiation can be observed easily as a shimmer of blue light from the water in boiling- and pressurized-water reactors, or spent fuel storage pools. In this research, we fabricated the fiber-optic Cerenkov radiation sensor using a Gdfoil, rutile crystal and optical fiber for detecting neutrons.

Understanding the Radiation Effects on Fiber Optic Sensors
2022In this dissertation, the effects of radiation (gamma, neutron or mixed gamma and neutron) on optical fiber sensors are studied and new techniques for real-time measurement of radiation-induced macroscopic changes in optical fibers are presented. It is crucial among the research and development efforts in the nuclear energy field to conduct experiments

A fiber-optic twin sensor for dose measurements in radiation therapy
Optical Review, 1996The developed fiber-optic twin sensor allowsin- vivo dose measurement in the tissue of the patient’s body. It consists of two radiation-sensitive fibers. The radiation-induced attenuations of these fibers are used to determine the dose absorbed in tissue.

Amplitude-time characteristics of a fiber optic ionizing radiation sensor
SPIE Proceedings, 1999In work the formulas for calculation of the amplitude-time characteristics of a Cherenkov fiber-optic ionizing radiation sensor are given. The results of the mathematical modeling which has been carried out on these formulas, coincide qualitatively with experimental data.

Optical Fiber Sensors Conference 2020 Special Edition, 2021
We have developed a fiber-optic low-coherence interferometric sensor with an all-fiber based quadrature phase shifted demodulator. The sensors have been applied to measure megahertz dynamic strains in a high radiation environment.

2015 15th European Conference on Radiation and Its Effects on Components and Systems (RADECS), 2015
Raman distributed temperature sensor (RDTS) measurements were performed during γ-radiation on three different classes of standard multimode fibers (pure, Ge-doped and F-doped). The sensor response is affected by the radiation induced attenuation phenomena leading to errors in the temperature measurements. The amplitude of this error strongly depends on

Fiber Optic Sensors as Dosimeters for Ionizing Radiation
1987The starting point of our investigations was the impact of ionizing radiation emerging from natural sources on fiber optic waveguides. Some of them showed a great sensitivity resulting in a darkening of the glass when exposed to ionizing radiation. The idea was to use this effect (unwanted in optical communication- systems) for a new type of radiation ...
