Quantitative holography is an accepted technology used in the aerospace industry to quantify reliability and performance of structures prior to their deployment and use. Holography is capable of measuring static and dynamic deformations with nanometer resolution, enabling characterization of structural dynamics and defects. An existing holographic testing system for large samples relies on a fixed coordinate system, requiring the sample to be moved to different orientations using heavy machinery. This is costly and time consuming; therefore, there is a need for a more flexible approach to measure large samples. This project aims to develop a positioner capable of moving a holographic camera around a fixed sample while maintaining the mechanical stability required to obtain accurate optical measurements. The necessary degrees of freedom were identified, and a mechanism was chosen and modified through analytical computational and experimental methods. The resulting mechanism was applied to test components and demonstrate the required positioning and measuring capabilities.
