title: Optical fiber measurements of particle velocity using laser-induced phosphorescence.
abstract: An optical fiber anemometer that uses laser-induced phosphorescence to measure particle time of flight in dense gas-solid suspensions is described. The anemometer is tested using a spinning disk coated with a phosphor having a persistent afterglow. The diagnostic technique is illustrated by measuring the velocity of free-falling particles coated with the same phosphor. Monte Carlo simulations are employed to determine the optical characteristics of the probe, including its measurement volume.
