Abstract
UN ESCANER ELECTRO-OPTICO, RETRO-REFLECTOR (10) TIENE UN DIODO LASER (18) QUE DIRIGE UN RAYO DE LUZ SOBRE UN ESPEJO OSCILANTE (22). EL RAYO DE LUZ DEL ESPEJO INCIDE SOBRE LA INDICACION A LEER, Y LA LUZ ES REFLEJADA HACIA ATRAS A LO LARGO DE UN CAMINO DE RETORNO (26) HACIA EL ESPEJO (22). DESPUES DE LA REFLEXION ADICIONAL EN EL ESPEJO, LA LUZ ALCANZA UN DETECTOR (24). CON LA PRESENTE INVENCION, SE ELIMINA COMPLETAMENTE LOS DISPOSITIVOS OPTICOS DE RECOGIDA QUE HABITUALMENTE SE ENCUENTRAN INCLUIDOS EN EL CAMINO DE VUELTA DE LA LUZ.
