Abstract

UN SENSOR DE DESPLAZAMIENTO OPTICO ES UTILIZADO PARA MEDIR EL DESPLAZAMIENTO GIRATORIO ENTRE DOS EJES (2, 4) QUE GIRAN JUNTOS. CONECTANDO LOS EJES JUNTOS POR MEDIO DE UNA BARRA DE TORSION (6), EL SENSOR PUEDE UTILIZARSE PARA MEDIR LA FUERZA DE TORSION TRANSMITIDA. EL SENSOR COMPRENDE UN PRIMER Y UN SEGUNDO DISCO COAXIALES (10,. 12) MONTADOS SOBRE LOS EJES (2, 4) Y QUE TIENEN RANURAS (16, 18) FORMADAS EN LOS MISMOS. UNA FUENTE DE LUZ (20) DIRIGE LUZ A TRAVES DE LAS RANURAS SOBRE UNA MATRIZ (22) DE FOTODETECTORES Y UN PROCESADOR DE DATOS (24) DETERMINA EL DESPLAZAMIENTO O LA FUERZA DE TORSION A PARTIR DE LAS POSICIONES SOBRE LA MATRIZ (22) DE LAS IMAGENES DE LOS BORDES DE LAS RANURAS.
