Abstract

UN APARATO OPTICO DE PRUEBAS NO DESTRUCTIVAS INCLUYE UN DISPOSITIVO INTERFEROMETRO MACH-ZEHNDER BIARMADO RECORTADO (1) Y DOS MEDIOS DE REGISTRO SEPARADOS (2,3). CUATRO CAMBIOS DE FASE DESPLAZADOS LATERALMENTE QUE MARCAN LAS IMAGENES PATRON DE UN MATERIAL, SON RECOGIDAS ANTES DE PRESIONARLES Y CUATRO CAMBIOS DE FASE DESPLAZADOS LATERALMENTE QUE MARCAN LAS IMAGENES PATRON SON RECOGIDAS DESPUES DE PRESIONARLAS. EL CAMBIO DE FASE ES EFECTUADO POR MEDIO DE UN TRANSDUCTOR PIEZOELECTRICO MONTADO EN UN ESPEJO (11) EL CUAL INCREMENTA LA LONGITUD DEL CAMINO DE UNO DE LOS BRAZOS DEL DISPOSITIVO (1). DE ESTA MANERA CUATRO IMAGENES SUCESIVAS SON GENERADAS Y GRABADAS SOBRE LOS MEDIOS DE REGISTRO SEPARADOS (2,3) CON UN SIMPLE CAMBIO DE FASE. LAS CUATRO IMAGENES PATRON MARCADAS Y RECOGIDAS ANTES DE LA PRESION, SON UTILIZADAS PARA DERIVAR UN PERFIL DE FASE MARCADO COMO SON LAS CUATRO IMAGENES TOMADAS DESPUES DE LA PRESION Y DOS PERFILES DE FASE MARCADOS SON DIFERENCIADOS PARA REVELAR LOS DEFECTOS DEL MATERIAL.
