Molecular rotational diusion detected by dierential fluorescence energy
(2000-03-01)
In this paper, we present a complete study of the influence of the molecular rotational diffusion movement in the fluorescence signal when a sample is excited by two short pulses. The study includes the calculations of ...

Characterization of reference standards for dirt by Laser Ablation Induced Photoacoustics (LAIP)
(2009-07-23)
Measurements of surface cleanliness and dirt characterization are important problems in a wide range of processes in industry and production. Standard methods are in most cases cumber some laboratory procedures that must ...

Simple method for thickness measurement in opaque samples with a Michelson-Sagnac interferometer
(2008-04-24)
We present in this work a method to measure thicknesses of opaque samples. The technique combines the use of low coherence interferometry with a Michelson-Sagnac configuration. This ring set-up let us to measure both faces ...
