In order to overcome the shortage of the existing fiber grating displacement sensor in the
process of measuring bidirectional deformation of the foundation pit, which are the reduction …

A dual cross-axis interference polarization-maintaining fiber interferometer (DCAI-PMFI) for
simultaneous measurement of strain and temperature is proposed. By using the cross …

Fast, miniature temperature sensors are required for various biomedical applications. Fibre-
optics are particularly suited to minimally invasive procedures, and many types of fibre-optic …

We theoretically propose an ultracompact large-dynamic-range dual-parameter sensor
using a broad free spectral range (FSR) multimode photonic crystal nanobeam cavity (MM …

In the present work, the effect of gamma radiation on the performance of different types of
erbium-doped fibers (EDFs) when they are used in a fiber ring cavity (FRC) configuration is …

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 …

Temperature cross-sensitivity, which especially performs complicatedly and severely in fiber-
optic sensors composed of various materials, will significantly affect the stability and the …

Soil moisture content has always been an important parameter to control because it is a
deterministic factor for site-specific irrigation, seeding, transplanting, and compaction …
