Dimensional measurement with usage of computed tomography method

Application of Computed Tomography (CT) in dimensional metrology is a new and relatively unexplored field. Metrological CT devices enable measurement of both external and internal geometry and structure of measurement objects with use of non-contact and non-destructive scanning method. It is a method with more advantages than disadvantages which makes it very desirable in the field of dimensional measurements and its wide use in different industries. The paper explains computed tomography measurement process and presents example of coordinate measurement of aluminium plate.
