- Abstract
Computed tomography is a non-destructive method that uses the nature of X-ray in order to measure both inner and outer objects' geometry. Because of many advantages and possibilities of conducting both material analysis inspection and dimensional measurement in a non-destructive way, the method is increasingly represented in industry. However, the method is very complex and has a huge number of influence parameters that cause errors in measurement results. Consequently, the measurement uncertainty as well as metrological traceability in general case are not achieved. In order to minimize and eliminate systematic errors, the reference objects are used. The usage of reference object for the purpose of identification and compensation of systematic errors is a generally accepted approach to ensure traceability. This article gives an overview of existing reference objects used in dimensional metrology with computed tomography and presents a new reference object.
