Concise answers to the most frequently asked questions about optical strain gages and fiber bragg grating technology.
Fiber Bragg Gratings (FBGs) are classified based on their refractive index modulation profile, periodicity, and spectral response. The primary types include uniform, chirped, tilted, and phase-shifted FBGs,
Bragg grating in germanosilacate fibers exhibits a temperature decay dependency. Type I FBGs are found to present reasonable short term stability up to 300°C, whereas Type IIA gratings exhibit very
Type I Bragg grating. Furthermore, due to the photosensitivity type of the Bragg grating, the grating itself has a character-istic behaviour with respect o temperature erasure. Type I gratings can be erased at
Fiber Bragg grating technology is popularly used in measurements of various physical parameters, such as pressure, temperature, and strain for civil

The structure of the FBG can vary via the refractive index, or the grating period. The grating period can be uniform or graded, and either localised or distributed in a superstructure. The refractive index has two primary characteristics, the refractive index profile, and the offset. Typically, the refractive index profile can be uniform or apodized, and the refractive index offset is positive or zero. There are six common structures for FBGs;
