Filtro holográfico adaptado

Abstract

RESUMEN: Un Filtro Holográfico Adaptado (FHA) es un procesador óptico que permite realizar operaciones de correlación y convolución, las cuales se ven reflejadas en la aparición de patrones de intensidad a la salida del procesador. En este trabajo se evidencia la relación que existe entre el ángulo de incidencia de la onda plana usada en la creación del filtro holográfico, y la separación de los picos de intensidad que corresponden a cada una de las operaciones antes mencionadas; relación que es de suma importancia para la discriminación de la información. Asimismo, se muestra que mediante la información de correlación es posible llevar a cabo procesos de validación de información. Se presentan los cálculos teóricos y las simulaciones computacionales que demuestran la validez del método

ABSTRACT: Adapted Holographic Filter (FHA) is an optical processor that allows performing operations of correlation and convolution, which are evident in the appearance of patterns of intensity in the output of the processor. In this work, we evidence the relation that exist between the incidence angle of the wave plane used in the creation of the holographic filter, and the separation of the intensity picks that correspond to each one of the operations before mentioned; relation that is crucial for the discrimination of the information. Also, we show that by means of the correlation information is possible to carry out processes of information validation. Theoretical calculations and computacional simulations are presented to demostrate the validity of the method.
