- •
Nonlinear and uncertainty exist in FBG high temperature/large strain measurement.
- •
Bayesian nonlinear model is proposed considering nonlinear and uncertainty problems.
- •
Posterior PDFs of measured temperature/strain are used to evaluate performance.
- •
The propose method precisely measures high temperature/large strain using FBG.
