Abstract
In this paper, results of a 0.35 THz dynamic aperture imaging approach are presented. The experiments use an optical modulation approach and a single pixel detector at a standoff imaging distance of 1 m. The optical modulation creates dynamic apertures of 5-cm diameter with 2000 individually controllable elements. An optical modulation approach is used here for the first time at a large far-field distance, for the investigation of various test targets in a field-of-view of 8 × 8 cm2. The results highlight the versatility of this modulation technique and show that this imaging paradigm is applicable even at large far-field distances. It proves the feasibility of this imaging approach for potential applications like standoff security imaging or far field THz microscopy.
