Polarization Sensitive Terahertz Digital Holography

We report on a Terahertz imaging methodology that combines digital holography and polarimetry to characterize objects in transmission and reflection geometries on their geometrical and physical properties in the Terahertz region between 0.3 - 1.0 THz. Digital reconstruction methods are implemented to extract both amplitude and phase images of objects. The plane wave back propagation algorithms allow the polarization information of object-beam interactions to be extracted from the holograms.
