Venkata Reddy Mamidi,Srimannarayana Kamineni,L. N. S. P. Ravinuthala,Sai Shankar Madhuvarasu,Venkatapparao Thumu,Vengal Rao Pachava,Kishore Putha +6 more
TL;DR: A fiber Brag grating-based high temperature sensor together with a low cost, high speed and compact size interrogation system using a long period grating was designed, developed and tested as mentioned in this paper.
Journal ArticleDOI
Characterization of Encapsulating Materials for Fiber Bragg Grating-Based Temperature Sensors
Venkata Reddy Mamidi,Srimannarayana Kamineni,L. N. Sai Prasad Ravinuthala,Venkatapparao Thumu,Vengal Rao Pachava +4 more
TL;DR: In this article, an experimental study has been carried out for the characterization of encapsulating materials for fiber Bragg grating-based temperature sensors to prevent the formation of micro-cracks and devitrification on the fiber surface at elevated temperatures by making use of a rigid probe.
Journal ArticleDOI
Fiber Bragg grating-based hydraulic pressure sensor with enhanced resolution
TL;DR: In this article, a simple technique for hydraulic pressure measurement with enhanced resolution using a fiber Bragg grating (FBG) and a metal spring which acts as transducer was reported.
