    Abstract: A characteristic response of a medium to an excitation transient of predetermined duration which causes the medium to emit a series of signals over a period of time which is long relative to the duration of the excitation transient is assessed. The signals are detected and the duration of each interval between successive signals is measured. A relationship relating the interval between the excitation transient and the emission of each signal to the interval between each signal and the preceding signal in the series is derived to represent the characteristic response.

    Abstract: A non-invasive portable apparatus for analyzing the performance of gas-filled window glazing units is disclosed. The operation of the apparatus is based on discharging the spacing between the panels (2a, 2b) of the window glazing unit (1) by applying rapidly alternating electrical field to the spacing between the panels of the window glazing unit, on collecting and analyzing the emitted discharge light in different structural intervals. The discharge is created by a needle-like electrode (5), and the inner conducting layer (2a) of the glazing unit serves as another electrode. The localization of the discharge in the vicinity of the end of the needle-like electrode (5) makes it possible to collect the emitted light without routine adjustment of the optical system. In this case, factory-adjusted lenses (4a) can be used to collect the light from the discharge, and the collected light can be transported to light detectors (9a-9d) by using fiber optics (6), which eliminates influence of instability to the discharge geometry.

    Abstract: A method exites and determines a luminescence in an analyte sample which is located in contact with the waveguiding layer of an optical layer waveguide. The luminescence is generated by non-evanescent excitation in the volume of the analyte sample. Luminescence radiation generated in the immediate proximity of the surface of the waveguiding layer is conducted to a measuring device and determined after penetrating the waveguiding layer.

    Abstract: A method in which a multiplicative ratio approach is used to remove the effects of the unwanted background fluorescence when making fluoroescence polarization (FP) measurements rather than the conventional subtractive approach, thus preserving both the precision and accuracy of the FP measurements, is disclosed. The method comprises selecting an appropriate multiplicative ratio, then calculating the selected multiplicative ratio using sample measurements. The calculated multiplicative ratio is multiplied by an appropriate value in a standard FP measurement equation or an appropriate value in an equation derived from a standard FP measurement equation. After this, the corrected FP measurement is calculated. When such multiplicative ratios are applied to the appropriate value or values in an FP measurement equation, the effects of background noise can be reduced without decreasing the precision of the FP measurements.

    Abstract: In a method of spectrochemical depth-profile analysis of heterogeneous materials, a first burst of ablation laser pulses in a first beam is directed at a sample to form an ablation crater. A second single pulse or burst of laser pulses in a second beam having a smaller width than said first beam is then directed at the bottom of the crater so as to create a plasma that emits radiation representative of a component in the sample without a significant contribution from the walls of the ablation crater. The intensity of radiation from the plasma is measured and the concentration of the selected component is determined from the intensity of the radiation. The depth at which the measurement is taken is then evaluated and the above steps repeated to determined the evolution of concentration of said selected component as a function of depth.
