Abstract

A theoretical and experimental study of self-referencing fiber optic intensity sensors based on Michelson and on Mach-Zehnder configurations is conducted. Via the definition of the measurement parameter R, sensor linearity and sensitivity are analyzed. Theoretical and experimental results are compared, considering the problem of sensor design and optimization. The choice between the two configurations is addressed; the Michelson one is recommended for practical reasons. © 2000 Society of Photo-Optical Instrumentation Engineers.
