| Popis: | We present the first results of an optical modulation approach for 0.35 terahertz radiation imaging, applied at standoff distances using a Compressed Sensing protocol. We show that optical modulation approaches are applicable for imaging even at stand-off distances and discuss the achieved edge fidelity, the overall image quality and limiting factors for our specific approach. |
