T-Ray Computed Tomography

This invention is directed to techniques for obtaining and imaging three-dimensional objects using radiation in the terahertz (THz) spectrum and systems and associated methods for high resolution terahertz computed tomography. Although computed tomography is well known in X-ray radiographic imaging, a serious problem in reconstructing an image using THz computed tomography is that the THz wave does not satisfy the short wave limit as the X-ray satisfies in X-ray computed tomography.
