  author={Manuel A. Ballester and Heming Wang and Jiren Li and Oliver Cossairt and Florian Willomitzer},
We present a novel single-shot interferometric ToF camera targeted for precise 3D measurements of dynamic objects. The camera concept is based on Synthetic Wavelength Interferometry, a technique that allows retrieval of depth maps of objects with optically rough surfaces at submillimeter depth precision. In contrast to conventional ToF cameras, our device uses only off-the-shelf CCD/CMOS detectors and works at their na-tive chip resolution (as of today, theoretically up to 20 Mp and beyond…
