Abstract
APARATO OPTICO PARA LA MEDICION INCREMENTAL DE LONGITUDES UTILIZANDO LUZ DIFUSA. EL APARATO (20) OPTICO ES APLICADO EN UNA MAQUINA HERRAMIENTA, UTILIZANDO UNA RED EXPLORACION (26A) Y UNA RED DE MEDIDA (5) GRABADA EN LA ESCALA MOVIL, DE IGUAL PERIODO, Y UN DISPOSITIVO FOTORECEPTOR (9) EN LA SALIDA. LA FUENTE DE LUZ (2) ES UN LED DE APLICACION GENERAL QUE EMITE LUZ DIFUSA PARA OBTENER EL MAXIMO CONTRASTE EN LA SEPARACION (D) DE AMBAS REDES (5, 26A), Y MEDIANTE AL MENOS UNA LENTE (26B) PROYECTAR UN CAMPO DE FRANJAS DE INTENSIDAD LUMINOSA EN SU PLANO FOCAL (12) SOBRE UNA RED DE LECTURA (27) DE PERIODO REPRESENTATIVO DEL DESPLAZAMIENTO DE LA RED DE MEDIDA (5). EL APARATO (20) OPTICO ES ECONOMICO E INSENSIBLE A LOS ERRORES DE LA SEPARACION ENTRE REDES (5, 26A), Y LA SEÑAL LUMINOSA OBTENIDA ES FORMA PROXIMA A LA SENOIDAL, NO NECESITANDO DE ELEMENTOS SUPRESORES DE ARMONICOS ADICIONALES.
