Abstract

SE PRESENTA UN ESCANER DE RANGO COMBINADO Y UN METODO PARA LEER DE FORMA ELECTROOPTICA SIMBOLOS TALES COMO CODIGOS DE BARRAS QUE TENGAN PARTES CON DIFERENTES REFLECTIVIDAD DE LUZ QUE UTILIZA DOS SISTEMAS DE ILUMINACION OPTICA MEDIANTE DIODOS QUE SON OPTIMAMENTE ENFOCADOS PARA DIFERENTES RANGOS DE TRABAJO. UN PRIMER SISTEMA DE ILUMINACION LASER ESTA OPTIMIZADO PARA EL FUNCIONAMIENTO DE CONTACTO Y TIENE UN RANGO QUE SE EXTIENDE HASTA APROXIMADAMENTE DOS PIES. EL SEGUNDO SISTEMA DE ILUMINACION LASER ESTA OPTIMIZADO PARA UN RANGO MAYOR DE EXPLORACION DESDE APROXIMADAMENTE DOS PIES HASTA 17 PIES Y LOS DOS SISTEMAS DE EXPLORACION LASER ESTAN INTEGRADOS EN UN ESCANER DE LASER DE RANGO COMBINADO. EL ESCANER DE LASER DE RANGO COMBINADO INCORPORA EN EL MISMO CIRCUITERIA LOGICA QUE HACE POSIBLE QUE CUALQUIERA QUE LOS SISTEMAS DE ILUMINACION FUNCIONEN SEGUN SE REQUIERA PARA LA APLICACION DE EXPLORACION EN PARTICULAR. DEPENDIENDO DE QUE SISTEMA DE ILUMINACION LASER SE SELECCIONE, LA VELOCIDAD DE EXPLORACION DEL LASER (POR EJEMPLO LA AMPLITUD DE LA SEÑAL DE CONTROL PARA EL MOTOR DE EXPLORACION) ESTA CONTROLADA PARA LIMITAR LA FRECUENCIA DE LAS SEÑALES DE LUZ RECIBIDAS HASTA LA FRECUENCIA DE PROCESAMIENTO DE LA SEÑAL ESTANDAR Y DE LOS CIRCUITOS DE DECODIFICACION. LA EXPLORACION SE CONSIGUE CON UN ELEMENTO EN FORMA DE ESPEJO OSCILANTE COMUN IMPULSADO POR UN MOTOR DE EXPLORACION, Y LA AMPLITUD DE LA SEÑAL IMPULSORA DEL MOTOR DE EXPLORACION APLICADA ES MAYOR PARA EL PRIMER SISTEMA DE ILUMINACION LASER OPTIMIZADO PARA FUNCIONAR EN UN CORTO RANGO DE FUNCIONAMIENTO Y MENOR PARA EL SEGUNDO SISTEMA DE ILUMINACION LASER QUE FUNCIONA EN EXPLORACION DE UN RANGO MAYOR.
