Carl Zeiss provides a powerful computer tomograph named Metrotom.It is used for industrial quality assurance. The visibility of the workpiece, which is generally inaccessible to probing or optical sensors is possible by the new computer tomograph. The tomograph is capable to measure external features. It is also applied to check the structure of material. This allows the generation of CAD models. With this symbiotic combination of computed tomography and traditional metrology, the company has begun a new chapter in metrology - metrotomography. During this process, a computer tomograph uses X-rays to non-destructively and then accurately displays the results as a 3D image. X-rays go through an object and display it on a suitable detector. One can get the details of the object as a 2D image. The intensity of the image depends on the geometry and absorption properties. The 3D image is created by rotating the object 360 along its axis on rotary table and then converting this data to a 3D volume model. Assembly checks and damage analyses, material inspections, and porosity and degect analyses can be done by the Metrotomography.It is used to inspect parts up to 350 mm but it depends on the material, for eg, steel, alloys, ceramic and plastic.
