WP2: Provide increased accuracy for optical and CT measurements in industry (WP leader: PTB)

  • Development of suitable methods and workpiece-like reference standards suitable for optical sensors and CT to achieve traceability.

  • Development of numerical modeling in order to correct for systematic errors, and to enhance the accuracy of optical sensors and CT systems by optimising sensor parameters. The aim is to achieve measurement uncertainties < 100 nm (optical sensors) and < 1 µm (CT). Special attention will be paid to the influence of the material, in particular when objects consisting of several materials are measured, and the surface properties.
