Paper Abstract

An original probe design for multimode optical fiber sensors, making use of a transducer, is presented. The probe is constituted by two facing quarter pitch graded-index (GRIN) microlenses which confine the transducer: the first GRIN is fixed to the fiber, while the other has a reflecting end face. The resultant micro-optical system works as a "nearly autofocusing cavity", which improves the coupling between the fiber and the transducer and shows a relatively low insertion loss.
