Objective: To analyze the change in tooth color produced by two hydraulic and one resin-based sealers by means of spectrophotometry for 3 years. Methods: Forty maxillary anterior teeth were selected (n = 10 per group). Root canals were prepared by ro

The possibilities of the radio-frequency amplitude modulation of a low-coherence source for distance and displacement measurements are discussed. This intensity-based method, used within a Michelson interferometer, is a novel alternative to perform d

SOFO is a fiber optic sensor system that allows the monitoring of micrometer deformations over measurement bases up to a few meters. It is particularly adapted to measure civil structures built with conventional civil engineering materials (concrete,

In 1996, a concrete highway bridge near Geneva (Switzerland) was instrumented with more than 100 low-coherence fiber optic deformation sensors. The Versoix Bridge is a classical concrete bridge consisting in two parallel pre-stressed concrete beams s

In many concrete bridges, deformations due to static and dynamic loading are the most relevant parameters to be monitored in both the short and long term. Strain monitoring give only local information about the material behavior and too many of such

Civil smart structures often require displacement sensors with measurement bases between a few centimeters and a few meters with a precision of the order of 1/100 mm. Low-coherence interferometry offers these performances even for long-term measureme

A novel demodulation technique for performing dynamic de- formation measurements using a path-unbalanced Michelson interferom- eter is reported. The method is based on the rf amplitude modulation of a low-coherence source, and demodulation is achieve

A novel demodulation scheme for the ranging of reflective markers is presented. This method is useful for implementing in-line mul- tiplexing of displacement and temperature sensors based on low- coherence interferometry. It allows the discrimination
Fiber optic sensors have already demonstrated to be suitable for the monitoring of full-scale structures. Usually, most effort has been concentrated in improving the different sensing techniques and it remains often the problem of adapting the sensor
