MEASUREMENT METHOD BASED ON AN OPTICAL WAVEGUIDE SENSOR SYSTEM

摘要

A method for measuring a value change of a parameter at the sensing area of an optical sensor element. The method includes the steps:;changing the value of the parameter thereby detecting the position and position change of a first signal peak within the detection window of a detector as well as thereby detecting the position and the eventual position change of a second signal peak within the detection window of the detector, andcorrelating the position detections of first and second signal peak and correlating the position change detections of first and second signal peak and attributing a value and/or a value change to the correlated detections
