چکیده
Abstract In this work, a hybrid sensor based on silica capillary in balloon-like shape for simultaneous measurement of displacement and temperature is proposed the first time, to best our knowledge. The fabricated by splicing segment hollow core fiber between two single mode fibers (SMF) bending balloon with at top-center position. transmission scheme, SMF-capillary-SMF configuration excites an antiresonant (AR) guidance enhances Mach-Zehnder interferometer (MZI). different responses interferometers external variations are conducive application these parameters. Experimental results show that, length 1.2 cm 4 cm, AR insensitive its sensitivity 14.3 pm/°C, while MZI has 1.68 nm/mm twice temperature, 28.6 pm/°C. consists only one sensing element exciting same which makes it simple fabrication as well low cost.

Fiber Bragg grating sensor for simultaneous measurement of displacement and temperature.
A new approach to measuring displacement and temperature simultaneously by use of a specially designed isosceles triangular cantilevered beam as a strain agent is demonstrated. A fiber Bragg grating epoxied onto the beam surface is experimentally demonstrated to have a temperature sensitivity of ~0.113 nm/ degrees C below 60 degrees C and a displacement sensitivity of 9.24x10(-2) nm/mm .

A dual-parameter optical sensor has been realized by UV-writing a long-period and a Bragg grating structure in D-fiber. The hybrid configuration permits the detection of the temperature from the latter and measuring the external refractive index from the former responses, respectively. The employment of the D-fiber allows as effective modification and enhancement of the device sensitivity by cl...

متن کاملDielectric multilayer-based fiber optic sensor enabling simultaneous measurement of humidity and temperature.
A multilayer-based fiber optic sensor enabling simultaneous measurement of humidity and temperature is proposed and demonstrated. The sensitive elements were multilayer coatings consisting of nano-porous TiO(2) and SiO(2) films, which were deposited on fiber end-face to form a Fabry-Perot (F-P) filter structure. Relative-humidity (RH) sensing is correlated with the shift of interference fringe ...
