Terahertz digital holographic imaging of visibly opaque printed dielectrics

Conference Paper

© 2014 IEEE. Terahertz digital off-axis holography has been demonstrated as a non-destructive imaging tool for three-dimensional (3D) printed structures. Digital holographic reconstructions from two structures were used to measure the imager's modulation transfer function and to show that terahertz digital holography can provide submillimeter resolution images of visually opaque printed structures and map their interior. As a demonstration we report on the detection of embedded air voids and material inclusions that differ from the host material in their complex refractive indices.
