The Dimensional Metrology Group (DMG) at the National Institute of Standards and Technology (NIST) is performing research to support the development of documentary standards within ASTM E57 for the point-to-point performance evaluation of 3D imaging systems that use a spherical coordinate system. The currently proposed tests call for the evaluation of point-to-point performance of these systems by determining the measurement error between two derived points at a number of positions in the instruments work volume. A part of the proposed standard involves measurements along the ranging/radial direction of the instrument and work was performed at NIST to understand the suitability of various targets for this aspect of the standard. This paper will only discuss the variety of artifacts that were considered and investigated for use in these ranging test positions.
