    Abstract: The present invention provides a self-reference and tunable optical displacement transducer comprising an optical splitter, at least one transducing element and a self-reference element, where each of said transducing element and said self-reference element comprises a pair of optical fibers and a reception assembly between each pair of the optical fibers. One of the reception assembly and the second optical fiber of the transducing element are displaceable along the same axis and relatively with respect to each other while another reception assembly and the second optical fiber of the self-reference element are non-displaceable. Incorporation of the self-reference element into the present transducer enables monitoring and measuring crack size and integral strength of a structure without being affected by other environmental or external factors.
