Advanced dimensional measurement systems such as large volume laser scanners, triangulation sensors, fringe projection systems, and XCT systems are increasingly used in industry; yet there are no common test procedures for the evaluation of these devices and there is no clarity on how traceability to the SI is realized. This project aims to address these issues for medium and large volume non-contact measurement systems by developing comprehensive models of opto-mechanical errors and test procedures that capture these sources of error. Standardized test procedures that capture all error sources are a critical step in establishing measurement traceability and in facilitating commerce by allowing users and manufacturers to easily compare and verify instrument performance.
