“…The measurement result can be impacted by the undesirable external perturbations easily, because the sensing arm and the reference arm are so long in the sensor. A Michelson interfero meter (MI) fabricated by hollow optical fiber and bonded to a PZT was used in voltage measurement [8]. However, the phase shift noise in the MI could impact on the measurement.…”

We present an optical fiber voltage sensor by Michelson interferometer employing a Fabry-Perot tunable optical filter and the phase generated carrier demodulation algorithm. By mounting a Michelson interferometer fabricated by an optical fiber coupler on a piezoelectric transducer, a dynamic strain would be generated to change the phase difference of the interferometer when the measured voltage is applied on the piezoelectric. The phase generated carrier demodulation method was used to obtain the phase variation of the interferometer by applying demodulate signal on a Fabry-Perot tunable optical filter. The measured voltage can be obtained by the variation of the phase; the random phase shift in the interferometer and the intensity fluctuation of the light source of the sensor can be eliminated. The experiment results show that the relation between the phase variation and the voltage applied on the piezoelectric is approximately linear. The dielectric reliability of the sensor has been verified according to the IEC standard.Index Terms-Optical fiber voltage sensor, Michelson interferometer, Fabry-Perot tunable optical filter, Phase generated carrier 1530-437X (c)

“…The attached optical fiber could be of any type such as a singlemode fiber [2], a hollow fiber [3], or a fiber Bragg grating (FBG) [4]. Depending on the type of the fiber sensor employed the measurement of voltage can be carried out either using the interference between the reflected and incident signal measurement [2,3] or by measuring the reflected signal shifts [4] However these existing schemes require complex and expensive measurement systems to extract either the phase information or the wavelength information in order to measure the voltage. We have previously presented a singlemodemultimode-singlemode (SMS) structure based fiber-optic voltage sensor that utilized a ratiometric power measurement system [5].…”

Q2: Fiber-optic sensor Voltage sensor Macrobending loss Whispering Gallery Mode a b s t r a c tWe propose and demonstrate an optical voltage sensing scheme based on a macrobending optical fiber in a ratiometric power measurement system. This novel approach to sensing has not been utilized before and has the advantage that the sensor involves simple fabrication compared to existing fiberoptic voltage sensors. To prove the feasibility of such a fiber-optic sensor, a sensor for a voltage range from 0 $ 100 V is demonstrated, with a resolution of 0.5 V. The sensor is robust, linear, and shows a competitive measurement resolution. The sensor can be easily scaled to suit other voltage levels and be effectively combined with optical current sensors.

This article presents the experimental characterization of a mechanically induced long-period fiber grating (MLPFG) array sensor for measuring the amplitude and width of an applied weight as well as detecting its position. The MLPFG array sensor consists of an optical fiber placed between a rubber cover and a 45-cm-long metal bar with round Figure 6 Far field intensity maps versus frequency and elevation angle h in E-plane and measured radiation patterns in E-and H-planes at maximum gain frequency for different bias voltage applied: (a and b) 0 V-1.9 GHz, (c and d) 5 V-2.02 GHz, (e and f) 12 V-2.16 GHz, and (g and h) 24 V-2.31 GHz. [Color figure can be viewed in the online issue, which is available at wileyonlinelibrary.com]ABSTRACT: Using a coplanar waveguide (CPW) feed with a shortcircuiting stub, the fed circular slot antenna for W-band operation is presented. The obtained results show that the impedance bandwidth, which is determined by 10 dB return-loss of the proposed slot antenna, can reach to 21% with the center frequency at 94 GHz (80 GHz-100 GHz), and the gain achieves 3.05 dBi at 92 GHz with good radiation performance.
