title: Phosphor-based thermometry of rotating surfaces.
abstract: The use of phosphor thermometry in generator rotor temperature monitoring over the 60-150 degrees C range has been investigated, using measurements of the decay time of the visible emission stimulated in europiumdoped yttrium oxysulfide by UV laser excitation. A fiber-optic system for light delivery and collection has been designed and tested in laboratory measurements on a rotating disk. Measurements of the effect of oil and magnetic field on sensor performance are reported.
