    Notes: Abstract The possibilities and limitations of remote sample characterization using induced fluorescence are discussed. General equations for remote sensing of fluorescence are presented and discussed. The implications of different elements of a system for remote fluorescence sensing on different parameters of the equations are treated. Background light influence and signal processing are considered. Pulsed lasers, flashlamps and cw lamps as excitation sources are compared when matched to the proper detection scheme employing boxcar integration or lock-in detection. Model experiments have been performed to demonstrate different measurement strategies. Examples from remote oil-slick characterization are chosen as illustrations.

    Notes: Abstract The delayed coincidence photon counting technique, employing a picosecond tunable dye laser as an excitation source, has been used for accurate determinations of radiative lifetimes of excited states. Excitation from meta-stable states of sputtered atoms was employed. We obtained for Cu: τ(3d 10 4p 2 P 1/2 = 7.27(0.06) ns, τ(3d 10 4p 2 P 3/2) = 7.17(0.06) ns and for Fe: τ(3d 7 4p y 3 F 2)= 9.06(0.16) ns, τ(3d 7 4p y 3 F 3) = 9.06(0.13) ns and τ(3d 7 4p y 3 F 4) = 9.11 (0.16) ns. Also, the ability of this technique to record quantum beats at frequencies up to 1 GHz is demonstrated.
