Measuring the Invisible

Abstract

The term "metrotomography" is the result of the combination of metrology and tomography. Unlike traditional computer tomography, metrotomography goes beyond pure visual checks, offering the opportunity to accurately measure internal and external geometries of complex objects, using non-destructive procedures. The 3D model of the object is obtained by composing a sequence of images obtained through electromagnetic radiation during a 360° rotation of the object. The accurate and complete description of the micro scale detail of the object allows to perform analysis and tests that, in some cases, significantly reduce the timeframes in respect to traditional methods and in other cases allow investigations that couldn’t be completed until today.
