Abstract

PROCEDIMIENTO PARA LA MEDICION OPTOELECTRICA DE RECORRIDOS Y DE ANGULOS EN EL QUE SOBRE LA SUPERFICIE (12) DE UN OBJETO (10) A MEDIR SE DIRIGEN BAJO ANGULOS PREDETERMINADOS UNA PRIMERA Y UNA SEGUNDA RADIACION (13, 14) Y (61, 63) OPTICA QUE SE DIFRACTAN EN UN LUGAR DE INCIDENCIA COMUN SOBRE LA SUPERFICIE (12). EN UN EJEMPLO DE REALIZACION LAS DOS RADIACIONES (13, 14) Y (61, 63) PRESENTAN UNA FRECUENCIA DIFERENTE. EN OTRO EJEMPLO DE REALIZACION SE ALTERA LA FRECUENCIA DE AMBAS RADIACIONES (13, 14) Y (61, 63) AL MISMO TIEMPO Y UNA DE AMBAS RADIACIONES (13, 14; 61, 63) PRESENTA UNA MODULACION DE FASE. SE EVALUA LA ALTERACION DE FASE DE LA SEÑAL ENTREGADA POR EL SENSOR (18) CON RELACION A UNA SEÑAL DE REFERENCIA.
