Computed tomography (CT) is an aspiring contact‑free measurement method which allows the complete geometry of objects to be determined. This includes the inner and outer geometry and the surface texture, all of which are typically not fully accessible by other measurement methods. There are a broad range of applications for CT, which include macro‑ and microfabrication, the automotive and telecoms industries, and additive manufacturing.
To support dimensional metrology in advanced manufacturing in the future, this project will develop traceable CT measurement techniques for dimensions and surface texture. Open issues regarding traceability, measurement uncertainty, sufficient precision/accuracy, scanning time, multi‑material, surface form and roughness, suitable reference standards, and simulation techniques will be addressed through the project’s objectives.
