MEASUREMENT METHOD BASED ON AN OPTICAL WAVEGUIDE SENSOR SYSTEM

摘要

The invention relates to a method for measuring a value change of a parameter at the sensing area of an optical sensor element such method comprising 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 - correlating 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.
