dc.description.abstract | Imaging resolution at terahertz frequencies is limited by the diffraction limit of the optics where the focus spot size is approximately on the order of a wavelength. We demonstrate a novel imaging technique that achieves sub-wavelength resolution at terahertz frequencies. A parallel plate terahertz waveguide is used as a near field imaging aperture in a transmission and reflection geometry. The image data is collected as projections of the target and are in the form of a radon transform. A reconstruction algorithm has to be used to extract the image from those projections. This type of reconstruction is similar to reconstruction techniques used in X-ray computed tomography (CT). | |
