Abstract

Abstract-continuous scan mode offers a relatively higher data achievement rate than the step scan mode, so it is often used in continuous-wave terahertz imaging to improve the imaging efficiency. The large time constant of lock-in amplifiers also provides good noise attenuation; however, it might bring motion blur to some extent in continuous scan mode. To cope with the problem, an imaging restoration method, which identifies the motion-point spread function of the motion blur, was proposed. A modified spatial filter was used to restore the blurred image. The image quality is better than that obtained by a conventional Wiener filter evaluated by a modified no-reference motion blur metric.
