R&D Vision presented the Terabot project in partnership with the Laboratory IMS at the Paris Air Show. Terabot is a mobile platform that combines visible 3D imaging and terahertz tomography.
The combination of these techniques to perform non-destructive testing on complex aeronautical structures falls within the scope of the SAPHyR project headed by the ALPHA-RLH competitiveness cluster, the French “Waves of innovation” cluster, backed by the Nouvelle-Aquitaine region.
