Abstract

EL PROCESO SE CARACTERIZA EN QUE EMITE UN HAZ LUMINOSO (4) DE FRECUENCIA OPTICA MODULADA, EN QUE SE RECEPCIONAN DOS HACES O RAYOS LUMINOSOS (I, J) DEVUELTOS POR CADA UNA DE LAS SUPERFICIES (2,3) DE UNA PARED (1) DEL MATERIAL, EN QUE SE CREA UNA INTERFERENCIA ENTRE ESTOS (I.J) Y EN QUE SE DETERMINA LA DIFERENCIA DE OPERACION {DE} DE LA SEÑAL DE INTERFERENCIA. SE UTILIZA UN DIODO LASER COMO FUENTE DE ILUMINACION, ESTE SE MODULA POR UNA MODULACION DE LA FRECUENCIA OPTICA DEL HAZ. ENTRE LOS RAYOS DIFUNDIDOS POR LAS DOS PAREDES, SE SELECCIONAN DOS RAYOS PARALELOS. EL DISPOSITIVO DE LA INVENCION PERMITE EFECTUAR SOBRE CADA DETECTOR MEDICIONES SEPARADAS DE 0,3 MSEC. SE PUEDE ASI EXPLORAR TODOS LOS MILIMETROS DE LA PERIFERIA DE UNA BOTELLA EN ROTACION. APLICACION EN LAS BOTELLAS DE VIDRIO O DE PLASTICO CLARAS O COLOREADAS Y EN EL VIDRIO PLANO.
