Abstract

LA INVENCION SE REFIERE A LA MEDICION DE LA DIFERENCIA ENTRE INDICES DE REFRACCION DE DOS MEDIOS, CADA UNO ATRAVESADO POR UN HAZ LUMINOSO, SIENDO DICHOS HACES SUSCEPTIBLES DE GENERAR UNA FIGURA DE INTERFERENCIA CONSTITUIDA POR FRANJAS DE LA CUAL SE MIDE EL DESPLAZAMIENTO. SEGUN LA INVENCION, SE UTILIZA UN UNICO MEDIO PARA DETECTAR EL DESPLAZAMIENTO DE LAS FRANJAS DE LA FIGURA DE INTERFERENCIA, SE REALIZA UNA MODULACION DE FASE SOBRE AL MENOS UNO DE LOS HACES Y SE CONTROLA LA MODULACION CON EL FIN DE OBTENER UN DESLIZAMIENTO DE LAS FRANJAS DE LA FIGURA DE INTERFERENCIA.
