【 摘 要 】

More recently, the industrial CT equipment is used not only for non-destructive analysis but to perform geometrical size evaluations. The three dimensional, optical measurements made by CT are popular because the measurement time is much more less than by using traditional 3D measurement machines, furthermore the inner geometries can be determined by non-destructive manner. In this article the measurement error and uncertainty are investigated in a particular case where the test piece consists of two materials, aluminium and polymer.
