Analysis and design of an edge-technique-based Doppler wind lidar: practical assessment of a laboratory prototype

Muñoz Porcar, Constantino (Date of defense: 2013-02-22)

This thesis is the initial stage in the development of a range-resolving Doppler wind lidar. Atmospheric lidars emit pulsed laser radiation that after being scattered by air molecules and suspended aerosol particles is ...

Atmospheric compensation experiments on free-space optical coherent communication systems

Anzuola Valencia, Esdras (Date of defense: 2015-06-15)

In the last years free-space optical communications systems for wireless links have been proposed, studied, and implemented mainly due to the higher bandwidth that this technology is able to provide. Still, radio frequency ...

Characterization and design of coherent optical OFDM transmission systems based on Hartley Transform

Chochol, Marcin (Date of defense: 2013-11-25)

Nowadays, due to huge deployment of optical transport networks, a continuous increase towards higher data rates up to 100 Gb/s and beyond is observed. Furthermore, an evolution of the current optical networks is forecasted, ...

Concept design, analysis, and Integration of the new U.P.C. multispectral lidar system

Kumar, Dhiraj (Date of defense: 2012-07-16)

The increasing need for range-resolved aerosol and water-vapour atmospheric observation networks worldwide has given rise to multi-spectral LIDARs (Light Detection and Ranging, a synonym of laser radar) as advanced remote ...

Exponentiated weibull fading channel model in free-space optical communications under atmospheric turbulence

Barrios Porras, Ricardo (Date of defense: 2013-05-17)

Free-space optical (FSO) communications is drawing increasing attention as a promising technology to overcome bandwidth shortage, of an evermore crowded wireless marketplace. Currently radio-frequency (RF) technology ...

Lidar and S-band radar profiling of the atmosphere : adaptive processing for boundary-layer monitoring, optical-parameter error estimation, and application cases

Lange Vega, Diego (Date of defense: 2014-07-17)

This Ph.D. thesis addresses remote sensing of the atmosphere by means of lidar and S-band clear-air weather radar, and related data signal processing. Active remote sensing by means of these instruments offers unprecedented ...

Ultrashort laser pulse measurement for multiphoton microscopy

Amat Roldan, Ivan (Date of defense: 2013-06-21)

In this thesis, we address specific efforts towards developing the precise aspect of ultrashort laser pulse measurement in the context of biomedical research. The motivation for pursuing these new developments was triggered ...
