Optical Fibers and Optical Fiber Sensors Used in Radiation Monitoring
By their very nature, optical fibers and, by extension, intrinsic and extrinsic optical fiberbased sensors are promising devices to be used in very different and complex environments considering their characteristics such as: capabilities to work under strong electromagnetic fields; possibility to carry multiplexed signals (time, wavelength multiplexing); small size and low mass; ability to han...
متن کاملCryogenic Temperature Monitoring via Optical Pdms Sensors
PDMS micro-sensors coated onto an electrical wire are used to measure dynamic temperature variation at cryogenic range based on optical whispering-gallery mode (WGM) frequency shift principle. We designed a lab cryogenic cell via filling liquid nitrogen to create a stable low temperature down to 95K. The electrical wire is current carrying to simulate a working electrical/electronic component/d...
متن کاملMonitoring techniques for the manufacture of tapered optical fibers.
The use of a range of optical techniques to monitor the process of fabricating optical fiber tapers is investigated. Thermal imaging was used to optimize the alignment of the optical system; the transmission spectrum of the fiber was monitored to confirm that the tapers had the required optical properties and the strain induced in the fiber during tapering was monitored using in-line optical fi...
متن کاملNovel laser machining of optical fibers for long cavities with low birefringence.
We present a novel method of machining optical fiber surfaces with a CO₂ laser for use in Fiber-based Fabry-Perot Cavities (FFPCs). Previously FFPCs were prone to large birefringence and limited to relatively short cavity lengths (≤ 200 μm). These characteristics hinder their use in some applications such as cavity quantum electrodynamics with trapped ions. We optimized the laser machining proc...
متن کاملChemical Sensing Using Microbent Optical Fibers
Introduction Microbend loss has always been an undesirable effect causing problems in fiber optic communication links. However, this phenomenon has been exploited profitably in fabricating a variety of fiber optic sensors [1-46] and in other applications such as development of mode strippers and mode scramblers [47], mode filters, phase shifters [48,49], signal processing [50] etc. The sensing ...
