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|
