Abstract

SE PRESENTA UN METODO PARA ANALIZAR UNA IMAGEN OPTICA DE UNA ESCENA PARA DETERMINAR LA INTENSIDAD ESPECTRAL DE CADA PIXEL DE LA ESCENA, EL METODO INCLUYE LA RECOGIDA DE LA LUZ INCIDENTE DE LA ESCENA; B) EL PASO DE LA LUZ A TRAVES DE UN INTERFEROMETRO QUE EMITE LUZ MODULADA QUE SE CORRESPONDE CON UN CONJUNTO PREDETERMINADO DE COMBINACIONES LINEALES DE LA INTENSIDAD ESPECTRAL DE LA LUZ EMITIDA DESDE CADA PIXEL; EL ENFOQUE DE LA LUZ EMITIDA DESDE EL INTERFEROMETRO SOBRE UNA MATRIZ DE DETECTORES; Y EL PROCESAMIENTO DE LA SALIDA DE LA MATRIZ DE DETECTORES PARA DETERMINAR LA INTENSIDAD ESPECTRAL DE CADA PIXEL DE LA MISMA. SI EL INTERFEROMETRO ES DE TIPO MOVIL SE REQUIERE LA EXPLORACION EN UNA DIMENSION CUANDO LA MATRIZ DE DETECTORES ES UNIDIMENSIONAL, Y NO SE REQUIERE EXPLORACION CUANDO LA MATRIZ DE DETECTORES ES BIDIMENSIONAL. SI EL INTERFEROMETRO ES DE TIPO NO MOVIL SE REQUIERE LA EXPLORACION EN UNA DIMENSION CUANDO LA MATRIZ DE DETECTORES ES BIDIMENSIONAL, Y EN DOS DIMENSIONES CUANDO LA MATRIZDE DETECTORES ES UNIDIMENSIONAL.
