Abstract

SE DIRIGE ENERGIA LUMINOSA INFRARROJA Y VISIBLE A TRAVES DE UN RECIPIENTE HACIA UNA CAMARA CCD QUE ES SENSIBLE A LA ENERGIA LUMINOSA TANTO VISIBLE COMO INFRARROJA. POLARIZADORES CRUZADOS SE ENCUENTRAN EN LADOS OPUESTOS DEL RECIPIENTE, Y ACTUAN SOBRE LA ENERGIA LUMINOSA VISIBLE DE MANERA QUE BLOQUEA LA TRANSMISION DE LUZ VISIBLE HACIA LA CAMARA EN AUSENCIA DE VARIACIONES DE TENSION EN EL RECIPIENTE, LO CUAL ALTERA LA POLARIZACION DE LA ENERGIA LUMINOSA VISIBLE QUE SE DESPLAZA A TRAVES DEL RECIPIENTE. POR OTRO LADO, LOS POLARIZADORES EJERCEN POCO O NINGUN EFECTO SOBRE LA ENERGIA INFRARROJA, LO CUAL CREA EN LA CAMARA UNA INTENSIDAD DE LUZ DE FONDO GENERALMENTE GRIS. DE ESTA MANERA, LA INCIDENCIA DE LUZ VISIBLE SOBRE LA CAMARA DEBIDO A VARIACIONES DE TENSION EN EL RECIPIENTE APARECE COMO UNA SENAL BRILLANTE CONTRA UN FONDO GENERALMENTE GRIS, MIENTRAS QUE EL BLOQUEO DE LA LUZ INFRARROJA DEBIDO A VARIACIONES OPACAS EN EL RECIPIENTE APARECE COMO UNA SENAL OSCURA CONTRA EL FONDO GENERALMENTE GRIS
