Abstract

DISPOSITIVO PARA VERIFICAR ERRORES SUPERFICIALES E INCLUSIONES NO METALICAS EN PIEZAS DE CONSTRUCCION DE MATERIAL TRANSPARENTE, QUE EXPLORA LA PIEZA DE CONSTRUCCION MEDIANTE RADIACIONES DE LUZ MOVIBLES YA QUE LAS PIEZAS DD CONSTRUCCION PRODUCEN UN CORTE DE LUZ. ESTE CORTE DE LUZ SE OBSERVA MEDIANTE UN MECANISMO INSTALADO EN LA DIRECCION DE INCIDENCIA DE LOS HACES DE LUZ. ESTE MECANISMO CONTIENE UN SISTEMA OPTICO FORMADOR DE IMAGENES QUE LLEVA INSTALADO EN SU PLANO DE FORMACION UN FILTRADOR DE IMAGENES CAMBIABLE PARA LA SEPARACION DE LAS IMAGENES PLANAS DE LAS PIEZAS DE VERIFICACION. LAS RADIACIONES DE LUZ ATRAVIESAN EL FILTRADOR DE IAMGENES Y SE LLEVAN A UN RECEPTOR CONECTADO A UNA DISPOSICION DE VALORACION DE LAS SEÑALES RECEPTORAS. MEDIANTE UN DISPOSITIVO SEMEJANTE SE DETERMINAN LOS ERRORES SUPERFICIALES DE LAS PIEZAS DE CONSTRUCCION POR SU LADO DELANTERO Y TRASERO. PARA PODER COMPROBAR ERRORES SUPERFICIALES ANISOTROPICOS ESTA PREVISTO UN TERCER SISTEMA RECEPTOR CONFORMADO COMO OPTICO INTEGRAL CONSISTENTE EN VARIOS RECEPTORES INSTALADOS EN UNA MEDIA CIRCUNFERENCIA QUE ABARCA LA PIEZA A VERIFICAR.
