<p>A fibre optic sensor 1 comprises a body 2 of a matrix material which includes an embedded length of optical fibre 3. When the body 2 is exposed to an external disturbance, mechanical and strain forces arising internally can be transmitted to the fibre 3 and will modify the passage of light therein. Pulsed light through the fibre 3 can be sensed for example by interferometry to measure the disturbance. This can provide an inexpensive and sensitive sensor construction which is capable of the remote detection of various parameters.</p> |
