Abstract

The design and operating parameters of a new class of continuously distributed optical fibre sensor are described. Using counter-propagating pulses, two-photon excitation of fluorescence from ions doped into the fibre enables any position to be monitored. By this means temperature or strain may be sensed with high spatial and temporal resolution. As the doped fibre is transparent for single photon absorption at the wavelength of the light pulses, attenuation does not set an upper limit to its length.
