Abstract
This paper discuss a set of tools for metrological evaluation of optical
fiber grating sensors, including uncertainty analysis of the measurements.
Background and definitions about basic specifications of the optical fiber
grating sensors, such as response curve, calibration curve, sensitivity,
resolution, repeatability, reproducibility and conformity are presented.
Besides, the paper proposes the procedures to identify, quantify, and
express uncertainties in optical fiber grating sensor measurements based on
the International Standard Organization's Guide to the Expression of
Uncertainty in Measurement. In order to illustrate the application of the
approach, two fiber grating measuring systems were evaluated under the light
of the methodology. The proposed route is a pragmatic step towards the
standardization of optical fiber sensors.
