The problem of static calibration of measuring systems is considered in a case where the raw result of measurement depends both on a scalar measurand and on a scalar influence quantity. An algorithm for calibration of a thermally self-compensated fiber-optic sensor of pressure is proposed. It is based on the use of cubic B-splines for modeling the nonlinearity of the dependence of the raw result of measurement on pressure, and the use of a low-order polynomial for modeling its dependence on temperature
