Abstract

EL DETECTOR COMPRENDE UNA UNIDAD DE CALIBRADO (3) OPTOELECTRONICA Y UNA REGLA TRANSPARENTE (2) CON DOS PISTAS DE GRADUACIONES PARALELAS (4, 5). UNA PISTA (5) ES DE INCREMENTO PROGRESIVO DE PASO CONSTANTE Y LA OTRA PISTA (4) ES DE GRADUACION SEUDOALEATORIA QUE FORMA BITS DE CODIFICACION BINARIA QUE CONSTITUYEN UNA SERIE CONTINUA DE PALABRAS DISTINTAS UNAS DE OTRAS, ESTANDO EL ANCHO DE UN BIT EN FUNCION DEL PASO DE INCREMENTO PROGRESIVO. LA PISTA INCREMENTAL (5) ES LEIDA A TRAVES DE UNA PISTA DE UN RETICULO DE CALIBRADO (9) POR FOTODETECTORES (8) DESFASADOS DE 90 EL PASO DE ESTA PISTA. LA PISTA (4) DE GRADUACION SEUDOALEATORIA ES LEIDA POR UN DETECTOR CCD (11) A TRAVES DE UNA LENTE (13) DE AUMENTO DE IMAGEN. LAS SEÑALES GENERADAS SON TRATADAS POR CIRCUITOS (15A, 15B) QUE ASEGURAN LA COMBINACION DE LA INFORMACION EXTRAIDA DE LAS DOS PISTAS DE LA REGLA.
