Abstract

A remote fiberoptic-based temperature sensor capable of operating above 1000 degree(s)C, based upon a hemispherical solid etalon, is described. Low-coherence techniques are used to interrogate the sensor, significant improvements in the signal-to-noise ratio have been achieved using a multimode laser rather than a conventional low-coherence source.
