Paper Abstract

A method of wavelength division multiplexing (WDM) for fiber optic sensors using a broadband light source and narrow bandpass thin film optical filter coatings on cylindrical graded index lenses has been developed. The WDM system is characterized by parallel information from all channels in real time. The system is being applied to a digital, rotary, absolute position encoder.
