Journal ArticleDOI
All-fused-silica miniature optical fiber tip pressure sensor
TL;DR: An all-fused-silica pressure sensor fabricated directly onto a fiber tip of 125 microm diameter is described, which may be suitable for medical diagnostics, environmental monitoring, and other industrial applications.
Journal ArticleDOI

Bing Qi,Gary Pickrell,Juncheng Xu,Po Zhang,Yuhong Duan,Wei Peng,Zhenyu Huo,Hai Xiao,Russell G. May,Anbo Wang +9 more
TL;DR: In this article, a data processing method for demodulating the information from the interference spectrum of a white light system is presented, and a compact white light interferometric system employing this algorithm has been developed, combined with fiber Fabry-Perot sensors.
Journal ArticleDOI
A novel temperature-insensitive optical fiber pressure sensor for harsh environments
TL;DR: A diaphragm-based miniature optical fiber pressure sensor has been shown to work at temperatures up to 700/spl deg/C with a sensitivity of 2.93 nm/psi and a resolution of 0.01 psi (68.9 Pa) as mentioned in this paper.
Patent
Optical fiber pressure and acceleration sensor fabricated on a fiber endface
TL;DR: A fiber optic sensor has a hollow tube bonded to the endface of an optical fiber, and a diaphragm attached to the hollow tube as discussed by the authors, which can be used for measuring pressure or acceleration in high temperature, high pressure and corrosive environments.
Proceedings ArticleDOI
