We present two different methods for measuring waves from the information provided by the speed log meter onboard. The first method processes data in the time domain, and is based in the measurement of the standard deviation ...

The lognormal (LN) and gamma–gamma (GG) distributions are compared to simulated and experimental data of the irradiance fluctuations of a Gaussian beam wave propagating through the atmosphere along a horizontal path, ...

La presente obra pretende proporcionar al estudiante una base sólida de conocimientos y conceptos de teoría electromagnética, que le permita acceder posteriormente a la comprensión de otros temas más avanzados, como los ...

From the expressions by Adrian and Earley (Proceeding of Minessota Symposium on Laser Anemometry, University of Minessota, Dept. of Conference, Minneapolis, 1976), we have calculated the signal-to-noise ratio of a Laser ...

The guided-to-leaky hybrid mode transition in slab optical waveguides made on uniaxial crystals such as LiNbO/sub 3/, or LiTaO/sub 3/, is analyzed. Two different guided-to-leaky transitions have been identified, namely the ...

In this paper we present the measures of the profile or velocity gradient of a liquid (water) across a circular section pipe in laminar state, by means of a two-dimension laser radar system (2D-LDA) designed by the ...

Temporal analysis of the irradiance at the detector plane is intended as the first step in the study of the mean fade time in a free optical communication system. In the present work this analysis has been performed for a ...

The superposition of noncoaxial light beams containing screw wave-front dislocations is shown to create light patterns with a richer vortex content than that given by the arithmetic of the topological charges of the ...
