Abstract
The various embodiments described here comprise an OFDR system and technique that may be used for inference of strain or temperature over a large dynamic range using a narrow wavelength range. Embodiments of the sensor fiber may be composed of one or more multi-spectral-feature sensors, each sensor exhibiting several spectral features that together offer coverage over a wavelength range corresponding to the desired system strain and or temperature dynamic range.
