Paper Abstract

This paper describes an attractive approach for referencing fiber optic intensity sensors in mobile platforms where variations of source, fiber path, or receiver parameters can severely compromise measurement of the desired parameter. The approach, named Time Domain Intensity Normalization (TDIN), operates with a wide variety of intensity-based sensors and also provides a means for sensor multiplexing. It therefore can serve as the basis for a standard fiber optic sensor system interface. Various reference schemes for intensity sensors are compared, followed by discussion of optical and electronic design implementation of TDIN, including system multiplexing. Theoretical analyses of key performance issues and test results (using a position sensor mechanism) are discussed.
