An optically controllable 0.35 THz single-pixel camera for millimeter resolution imaging

Abstract

We present a single detector THz imaging system with millimeter spatial resolution that operates without any mechanical movements of the detector and the THz optics. The imaging system, an optically controllable 0.35 THz single-pixel camera, is used in transmission mode to image binary targets. The typical size of the targets is several centimeters diameter and the acquisition time for such targets is less than 2 minutes. The software reconstruction of the acquired signals yields images with more than 2500 pixels, respective < 1 mm spatial resolution. As an outlook first results obtained with the camera's radar-reflection mode will be presented.
