The uncertainty in the measured fluorescence decay lifetimes of 30 nm particles of YAG:Cc was used to evaluate the predictions of a novel form of the Heisenberg uncertainty principle suggested by de Sabbata and Sivaram, ΔT Δt ≥ h/k. The worst-cas

This test established feasibility for on-the-fly temperature measurements of railgun projectiles. In addition, an approach for projectile velocity measurement was also demonstrated. Insight was gained into other useful optical and fiber optic diagnos

A novel form of the Heisenberg uncertainty principle, as introduced by de Sabbata and Sivaram, ∆T∆t ≥ ħ/k, was tested using laser-induced fluorescence of 30 nm particles of YAG:Ce. The temperature-dependent fluorescence decay lifetimes of this

Described here are efforts to diagnose transient pressures generated by a short-pulse (about 0.5 microseconds) high intensity proton ({approximately} 2 * 10 14 per pulse) beam. Proton energy is 800-MeV. The tests were performed at the Los Alamos Neut

A method for measuring the emission spectra of diamond wafers, typically 0.1 to 1 mm thick, is described. The method uses a 40 W continuous CO laser (1800 cm−1 to 1900 cm−1) to heat the diamond to ∼500 °C suspended in an evacuable cell in an e

Introduction R is under way to measure the temperature of surfaces within operating turbine engines. To supply these measurements, which are necessary for some Air Force programs, current efforts are concentrating on the first-stage rotor blades and
