Long-range dual-band compressive sensing camera

Abstract

Compressive sensing (CS) imaging is a computational imaging technique that has the potential to reconstruct a highresolution image from signals acquired by low-resolution detectors with one or a few elements. This paper presents a mobile dual-band CS system developed at Fraunhofer IOSB. The system has the capability of simultaneous image acquisition in two spectral bands between 0.35 µm and 2.9 µm. Furthermore, CS measurements in the visible (VIS) and short-wave infrared (SWIR) spectral range at distances of up to 27 km are demonstrated.
