Análisis fotométrico del cúmulo abierto ngc 6611
(2006)
Se diseñaron programas en Matlab, que aplican el método de fotometría de apertura diferencial, a dos imágenes tomadas con un dispositivo de carga acoplada (CCD) en los filtros visible V y azul B, para calcular los parámetros ...
Alineamiento de pasos ópticos extensos, basados en una rejilla de diffraction de fase desenfocadora
(2004)
In a long baseline stellar interferometer, the optical beams are guided over several hundred meters by steering mirrors and generally propagated under vacuum. There is an urgent requirement to provide a simple mechanism ...
Understanding the atmospheric turbulence structure parameter, Cn2, in the littoral regime
(2006)
Understanding optical propagation through atmospheric turbulence is a highly important step for the efficient implementation of a free space laser communication system and for achieving diffraction limited imaging over ...
Stellar imaging interferometry
(2003)
This thesis work, developed at the laboratories of the Department of Physics of the University of Puerto Rico, reports the first efforts to build a prototype stellar interferometer with applications to stellar astrophysics. ...
Rejilla de defoco
(2003)
This thesis describes the design and manufacture of a non-conventional diffraction grating, referred to as a Defocus Grating. It was designed by adding to the equation of the lines of a standard grating, a function of ...
16 inch composite material telescope with adaptive optics.key components: wavefront reconstructor & vibration testing
(2006)
Advances in technology has provided means for astronomical optical telescopes to increase the aperture diameter (more light collecting capability) therefore increasing the resolution. Better resolution allows telescopes ...
