We present a novel single-shot interferometric ToF camera targeted forprecise 3D measurements of dynamic objects. The camera concept is based onSynthetic Wavelength Interferometry, a technique that allows retrieval of depthmaps of objects with optically rough surfaces at submillimeter depth precision.In contrast to conventional ToF cameras, our device uses only off-the-shelfCCD/CMOS detectors and works at their native chip resolution (as of today,theoretically up to 20 Mp and beyond). Moreover, we can obtain a full 3D modelof the object in single-shot, meaning that no temporal sequence of exposures ortemporal illumination modulation (such as amplitude or frequency modulation) isnecessary, which makes our camera robust against object motion.  In this paper, we introduce the novel camera concept and show firstmeasurements that demonstrate the capabilities of our system. We present 3Dmeasurements of small (cm-sized) objects with > 2 Mp point cloud resolution(the resolution of our used detector) and up to sub-mm depth precision. We alsoreport a "single-shot 3D video" acquisition and a first single-shot"Non-Line-of-Sight" measurement. Our technique has great potential forhigh-precision applications with dynamic object movement, e.g., in AR/VR,industrial inspection, medical imaging, and imaging through scattering medialike fog or human tissue.
