摘要

A method has been developed for nonintrusive collection of surface-temperature data from reactive and nonreactive surfaces. The method relies on the temperature sensitivity of the laser-induced fluorescence of a rare-earth ion which has been seeded into the material under study. The rare-earth ion (dysprosium) doped into a crystal (yttrium-aluminum-garnet) is shown to be an ideal seed, the fluorescence of which is stimulated by the ultra -violet output of a Nd:YAG laser. The fluorescence of the crystal is collected by a linear-array detector, analyzed, and stored for evaluation. Calibration of this method has been made from 300 to 1673 K. Tests have been conducted on reactive and nonreactive surfaces. Additionally, a technique for obtaining temperature depth profiles of reactive materials has been developed, and test results are shown.
