Abstract :
Multi-parameter sensing specialty fiber gratings are of crucial importance for nuclear industry due to their unique properties such as high radiation dose sensitivity, viability of operation up-to 1 MGy dose. We report on our unique in-situ dose measurements of Turnaround-point LPGs and their applications for strain and temperature measurements.
