Super-Resolution reconstruction for terahertz pulsed imaging
2017
Terahertz technology is one of emerging technologies that has a potential to change our life. There is considerable interest in using electromagnetic terahertz pulses for imaging purposes. In this paper we presented initial results for improving the resolution of terahertz pulsed imaging system utilizing methodology of super-resolution reconstruction. We attempt to reconstruct an super-resolution(SR) reconstruction terahertz image from four subpixel-shifted low resolution(LR) terahertz images acquired under the same experimental condition via the THz-TDS system. The experimental results are analyzed and discussed. It was shown in laboratory experiments that SR has good effect of reconstructing a SR terahertz image from multi-frame LR.
