Fabricating Information Inside Physical Objects for Imaging in the Terahertz Region

摘要

The infrastruct fabrication and imaging technique described herein uses digital fabrication techniques to embed information inside objects and THz imaging to later decode this information. Information is encoded in a digital model to create structured transitions between materials. Digital fabrication is used to precisely manufacture the digital model with material transitions enclosed internally. A THz Time-Domain Spectroscopy (TDS) system is used to create a volumetric image of the object interior. The volumetric image is processed to decode the embedded structures into meaningful information.
