Abstract

EL SISTEMA DE CAMARA (10, 100) DE LA PRESENTE INVENCION BUSCA SIMULTANEAMENTE CIERTOS OBJETIVOS DE ADQUISICION OPTICAS DIFERENTES (44). SOBRE LA DETECCION DE UN OBJETIVO DE ADQUISICION (44) SE DECODIFICA SEGUN LOS CORRESPONDIENTES ALGORITMOS DE DECODIFICACION POR DIFERENCIACION. PARA FACILITAR ESTA OPERACION HAY UN BUS DE SISTEMA (170) ASI COMO UN BUS DE DATOS DEDICADO (176) A APLICAR UNA SEÑAL DE EXPLORACION DE UN DISPOSITIVO DE EXPLORACION OPTICA (154) A UN CIRCUITO DE DETECCION POR DIFERENCIACION. ESTE SISTEMA PUEDE DECODIFICAR, POR EJEMPLO, TANTO CODIGOS DE BARRAS COMO ANILLOS CONCENTRICOS. LA SEÑAL DE EXPLORACION SE AJUSTA CONSTANTEMENTE SEGUN TANTO UNA REFERENCIA OSCURA PARA CORREGIR PARA CORREGIR EL DESVIO COMO UNA REFERENCIA BLANCA PARA CORREGIR LA GANANCIA. LA GANANCIA TAMBIEN SE CORRIGE SEGUN EL NIVEL DE EXPLORACION ASI COMO LA CANTIDAD DE ILUMINACION PRESENTE. UNA MEDICION DE ESTA ILUMINACION PUEDE SER APLICADA DIRECTAMENTE AL DISPOSITIVO DE EXPLORACION OPTICA (154) MEDIANTE UN CABLE DE FIBRA OPTICA (402) QUE TRANSMITE LUZ DESDE LA FUENTE DE ILUMINACION (15). CUANDO SE DETECTAN LOS ANILLOS CONCENTRICOS EL SISTEMA DE LA PRESENTE INVENCION UTIIZA PLANTILLAS ALMACENADAS QUE REPRESENTAN UN NUMERO DE TRANSFORMACIONES DEL OBJETIVO (44), POR EJEMPLO, UN NUMERO DE AUMENTOS. CUANDO LA TRANSFORMACION DE UNA OBJETIVO (44) ESTA DETERMINADO , LA PLANTILLA ALMACENADA CORRESPONDIENTE SE CORRELACIONA CON LA SEÑAL DE EXPLORACION DEL DISPOSITIVO DE EXPLORACION OPTICA (154). PARA DETECTAR ANILLOS CONCENTRICOS LA SEÑAL DE EXPLORACION ES APLICADA AL CIRCUITO INTERLAMINADOR (180) QUE CORRELACIONA MAS DE UNA EXPLORACION A LA VEZ PARA CONSEGUIR UN RENDIMIENTO CONSTANTE INCLUSO AUNQUE LAS ETAPAS DEL DETECTOR OPEREN A DIFERENTES VELOCIDADES. LA CALIBRACION OPTICA SE ELIMINA POR OPTICAS FIJADAS EN LAS QUE DE TODOS LOS ELEMENTOS OPTICOS ESTAN RIGIDAMENTE MONTADOS CON TOLERANCIAS MUY CERCANAS. LA FUENTE DE ILUMINACION (15) ESTA DISPUESTA SOBRE UN FOCO DE UNA ELIPSE (18) EN LA QUE EL OTRO FOCO(24) ESTA DISPUESTO A LA DISTANCIA MAXIMA DE EXPLORACION Y EL REFLECTOR (14) ESTA FORMADO PARA DEFINIR LA ELIPSE DE ILUMINACION (18) PARA MAXIMIZAR LA LUZ APLICADA AL OBJETO (42). LOS VARIOS ELEMENTOS DE PRODUCCION DE CALOR ESTAN DISPUESTOS EN COMPARTIMENTOS ESTANCOS (40A,B,C) QUE ESTAN REFRIGERADOS POR AIRE A PRESION QUE CIRCULA A TRAVES DE UN INTERCAMBIADOR DE CALOR. UN SISTEMA DE ENFOQUE EN TIEMPO REAL CONSISTE EN QUE LA DISTANCIA DESDE EL DISPOSITIVO DE EXPLORACION A UNA SUPERFICIE ABIERTA ESTA CONSTANTEMENTE CONTROLADA Y EL SISTEMA ESTA CONSTANTEMENTE ENFOCADO SEGUN LA DISTANCIA.
