It is shown that by controlling the level of hydrogen saturation, via hot and cold hydrogenation, it is possible to produce gratings with lower thermal coefficients. Furthermore, there is a larger difference between the Type 1 and Type 1A thermal coefficients and a significant improvement in the matrix condition number, which impacts the ability to recover accurate temperature and strain invariant data using the Type 1-1A dual grating sensor. | ISSN: | 0277-786X | DOI: | 10.1117/12.624287 | Rights: | © 2005 SPIE. | Type: | Conference Papers | Affiliation: | Higher Technical Institute Cyprus | Affiliation: | Higher Technical Institute Cyprus Photonics Research Group Aston University |
