Abstract
The present invention provides a method for normalization and calibration of a fiber optic pressure transducer wherein the normalization routine includes measuring the minimum and maximum light signals returning from the pressure transducer and adjusting the offset and the gain such that the difference is a predetermined constant and wherein the calibration method has steps including: measuring the light signals and the pressures associated therewith for a variety of pressures; evaluating the light signals at preselected intervals by averaging the light signal with the one preceding it and following it; constructing a table having the evaluated light signals and the pressure readings associated therewith.
