Combine Optical and Tactile Measurements

Combine Optical and Tactile Measurements for Sub-Aperture Form Evaluation

This study presents a hybrid approach that leverages NMF’s high-resolution optical scanning alongside tactile profilometry to enhance confidence in surface data, especially for sub-aperture and freeform applications. By comparing non-contact and contact measurement results, the team validates surface form data while compensating for coating and material effects that may influence results. This workflow underscores the NMF system’s value in cross-validation scenarios where data integrity is critical.
