Abstract

PROCEDIMIENTO Y APARATO PARA ANALIZAR UNA IMAGEN OPTICA DE UNA ESCENA A FIN DE DETERMINAR LA INTENSIDAD ESPECTRAL DE CADA PIXEL DE LA MISMA, QUE COMPRENDE CAPTAR LA LUZ INCIDENTE DE LA ESCENA; PASAR LA LUZ A TRAVES DE UN INTERFEROMETRO QUE PROPORCIONA EN LA SALIDA LUZ MODULADA CORRESPONDIENTE A UN CONJUNTO PREDETERMINADO DE COMBINACIONES LINEALES DE LA INTENSIDAD ESPECTRAL DE LA LUZ EMITIDA POR CADA PIXEL; ENFOCAR LA LUZ QUE SALE DEL INTEREFEROMETRO SOBRE UNA SERIE DE DETECTORES BIDIMENSIONALES; Y PROCESAR LA SALIDA DE LA SERIE DE DETECTORES A FIN DE DETERMINAR LA INTENSIDAD ESPECTRAL DE CADA PIXEL DE LOS MISMOS; EL INTERFEROMETRO ES DEL TIPO FABRY-PEROT QUE TRADUCE BAJA FINURA, EN EL CUAL LA DIFERENCIA DEL RECORRIDO OPTICO ES VARIADA PARA MODULAR LA LUZ TRADUCIENDO UN ELEMENTO DEL INTERFEROMETRO, DE MANERA QUE EN CADA INSTANTE CADA DETECTOR VE UN PUNTO DISTINTO DE LA ESCENA Y SU SEÑAL ES UNA COMBINACION LINEAL DEL CONTENIDO ESPECTRAL DE LA LUZ QUE PROCEDE DE CADA PIXEL, Y QUE CUANDO EL ESCANER COMPLETA UN BARRIDO DEL INTERFEROMETRO, LA ESCENA HABRA SIDO ESCANEADA EN TODAS LAS COMBINACIONES LINEALES RELEVANTES DEL CONTENIDO ESPECTRAL.
