Abstract
Research has been carried out showing that severe errors in the calibr ation of ruby fluorescence decay-time fiber optic thermometers, partic ularly in the cryogenic region (> 77 K), can occur if probes are not c arefully designed to avoid fluorescence reabsorption effects. This eff ect is investigated and quantified. (C) 1996 American Institute of Phy sics.
