We present experimental results in deformation measurement and thickness change in polymer films employing Fourier domain interferometry. The set-up is a Michelson configuration in which interference signal betweeen light ...

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 ...

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 ...

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 ...

Se describirá como se generan las señales de interferometria de baja coherencia en el espacio de Fourier, se determinara las características que determinan el rango dinámico del sistema y las señales asociadas al sistema ...
