Abstract

DISPOSITIVO INTERFEROMETRICO Y METODO PARA MEDIR Y PARA ESTABILIZAR LA LONGITUD DE ONDA DE DIODO LASER. EL DISPOSITIVO (1) SE ACOPLA A CUALQUIER SISTEMA OPTICO DONDE SE REQUIERA DISPONER DEL VALOR REAL DE LA LONGITUD DE ONDA, Y COMPRENDE UN ELEMENTO (9) OPTICO UNICO QUE SE INTERPONE DIRECTAMENTE EN EL CAMINO DEL HAZ (11) LASER OBTENIENDO DOS HACES (13, 14) CUYA DIFERENCIA DE CAMINO RECORRIDO ES CONSTANTE PORQUE ESTA LIMITADA AL INTERIOR DEL ELEMENTO (9); LA INTENSIDAD LUMINOSA DEL CAMPO INTERFERENCIAL ES LA UNICA VARIABLE EN EL CALCULO DE LA LONGITUD DE ONDA. SE APLICA EL DISPOSITIVO (1) PREFERENTEMENTE EN INTERFEROMETROS DE MAQUINA HERRAMIENTA QUE MIDEN DESPLAZAMIENTOS LONGITUDINALES.
