A smart interpolator is proposed to improve the long-term stability of a fiber-optic pressure sensor. This method relies on decomposing the compensation model into signal and reference channel parameters. Analysis shows that this interpolator can be used for self-calibration and cancellation of the long-term drift. Experiments prove its effectiveness.
