Paper Abstract

The long-term stability of intensity modulated fiber optic sensors under changing environmental conditions is limited by many factors. Introducing the spectral symmetric referencing method it is shown that even linear spectral variations of down-lead damping can be compensated. In combination with a simple modulator consisting of a spectral filter with locally varying density a novel position sensor has been realized. This design reduces the error caused by down-lead sensitivity to 2 %.
