A multi-longitudinal mode fiber laser sensor (MLMFLS) system based on neural network
(NN) algorithm is proposed. Gaussian process regression (GPR) is used to denoise the beat …

The on-line measurement of oil-film pressure inside a journal bearing based on an optical
fiber Bragg grating (FBG) is proposed and described for the first time. Two methods are …

We propose and verify a fiber optic temperature sensor whose demodulation method is
measuring the spectra contrast, which is quantified by the amplitude of the fast Fourier …

In this paper, we describe a novel temperature sensing system based on chaotic correlation
fiber loop ring down technique. A fiber Bragg grating is introduced into the fiber loop cavity …

In this paper, we propose and demonstrate a method for simultaneously measuring liquid
temperature and refractive index by using spontaneous Raman scattered light in a multi …

In the high precision molecular spectroscopy, the temperature of gas absorption cell is
accurately measured. In this paper we discuss the factors affecting the measurement …

An algorithm is proposed to interpret the oil temperature data collected by a Fiber Bragg
Grating sensor system installed inside the locomotive engines. In contrast to earlier attempts …

With the fast development of microgrids in more electric aircrafts and ships, the higher
reliability of signal acquisition and processing systems are required in the complex …

A new design scheme of photo-electrical rotary joint dynamic detection device is proposed,
which can simulate the actual working state of photo-electrical rotary joint and dynamically …
