| dc.description.abstract | En este trabajo se realizó un estudio para determinar la importancia de la relación relativa de las intensidades de la onda de referencia y la onda objeto en holografía digital en términos del contraste de la imagen holográfica reconstruida. Para ello se llevaron a cabo diferentes registros holográficos variando la relación de intensidades de la onda de referencia respecto a la onda objeto. Además de las reconstrucciones numéricas de estos registros holográficos, se hizo un análisis sobre los perfiles de intensidad de estos hologramas antes y después de realizado el requerido proceso de filtrado espacial. Los resultados obtenidos permiten concluir que contrario al proceso análogo de la holografía óptica tradicional, en holografía digital no es necesario mantener un alto control de las relaciones de intensidad entre la onda de referencia y la onda objeto. En general, se puede afirmar que esta relación de intensidades es de baja influencia para la calidad de la reconstrucción holográfica digital siempre y cuando que en el registro se respeten las adecuadas condiciones de muestreo y no saturación de los píxeles. | spa |
| dc.description.abstract | In digital holography with respect to the quality of the numerical reconstructions of the digitally recorded holograms. To perform the study, we have recorded several holograms of the same sample varying the ratio of intensities between the reference and object waves. In addition to the numerical reconstructions of these holograms, we have carried out an analysis of the intensity profiles of the digitally recorded holograms before and after performing the needed process of spatial filtering. The results of the numerical reconstructions and the analysis of the intensity profiles allow us to conclude that on contrary to the analogous process of optical holography, in digital holography is not necessary to keep a high control in the intensity ratio between the reference and object waves. In general, it can be stated that this relation of intensities is of low importance, while it is assured the correct sampling of the hologram and the no saturation of pixels are guaranteed. | eng |
