Interferometric and Synthetic Aperture Real-Time Terahertz Imaging

ORAL

Abstract

Over the past several years, several methods of real-time THz imaging have been developed. In this presentation, we describe a synthetic aperture imaging method of THz imaging. A 4-element THz detector array is used to reconstruct 2-D images of a point source through the interferometric synthetic aperture imaging method. A capture rate up to 63frames/s can be achieved. The recorded video showing the movement of the terahertz source in real time can be viewed at http://www.njit.edu/$\sim $ks265/imagingvideo.html after baseline and phase correction. Furthermore, a high power THz source will be integrated in this CW THz system for longer stand-off imaging distances.
