摘要

A multi-frame, super-resolution imaging algorithm for a THz array detector with parallel-pixel data acquisition is proposed to overcome both detector resolution limit and prolonged acquisition time. A correction scheme was also implemented to counteract a fixed-pattern variation caused by non-uniform pixel responsivity observed in our experimental results. The proposed technique aims to serve the demands for THz non-destructive testing (NDT) and quality control (QC) applications, which requires a rapid high-resolution THz imaging system.
