Cross-talk free and ultra-compact fiber optic sensor for simultaneous measurement of temperature and refractive index.
TL;DR: A cross-talk free simultaneous measurement system for temperature and external refractive index (ERI) implemented by dual-cavity Fabry-Perot (FP) fiber interferometer demonstrated, which showed that temperature could be determined independently from the spatial frequency shift without being affected by the ERI.
Journal ArticleDOI
All-fiber variable optical delay line for applications in optical coherence tomography: feasibility study for a novel delay line
TL;DR: The non-invasive cross-sectional images of biomedical samples as well as a transparent glass plate obtained with implemented all-fiber delay line having the axial resolution of 100 mum and the dynamic range of 50dB are presented to validates the imaging performance and demonstrate the feasibility of the delay line for optical coherence tomography.
Journal ArticleDOI
Simultaneous Measurement of Temperature and Strain Based on Double Cladding Fiber Interferometer Assisted by Fiber Grating Pair
TL;DR: In this article, a double cladding fiber interferometer consisting of a long-period fiber grating pair for simultaneous measurement of temperature and strain was presented, and it was shown that the relative phase of interference fringes is solely dependent on the strain, whereas the ambient temperature causes a shift in the envelope of the fringes.
Journal ArticleDOI
Fiber-Optic Probe Based on a Bifunctional Lensed Photonic Crystal Fiber for Refractive Index Measurements of Liquids
TL;DR: In this paper, a fiber-optic sensor for measuring the refractive index (RI) of a liquid sample is constructed from an extrinsic cavity formed by a micromirror and a lensed photonic crystal fiber (PCF) tip.
