Test Artefacts for the Verification of Optical Digitizers

Abstract:

To ensure the reliability of the measurement results with optical digitizers, it is necessary that the instruments are verified under proper protocols with traceably calibrated artefacts. The requirement for test artefacts is being calibrated with small uncertainty. In addition, it is needed that the optical characteristics of the artefacts' surface are suitable for the measurement with optical sensors because optical digitizers adopt different measuring methods. In this research, the concept, structure and feature of the test artefacts are reported.
