Exploiting wavelength diversity for high resolution time-of-flight 3D imaging
Fengqiang Li, Florian Willomitzer, Prasanna Rangarajan +1
State-of-the-art time-of-flight (ToF) based 3D sensors suffer from poor lateral and depth resolutions. In this work, we introduce a novel sensor concept that provides ToF-based 3D…

Synthetic Wavelength Holography: An Extension of Gabor's Holographic Principle to Imaging with Scattered Wavefronts
Florian Willomitzer, Prasanna V. Rangarajan, Fengqiang Li +3
The presence of a scattering medium in the imaging path between an object and an observer is known to severely limit the visual acuity of the imaging system. We present an approach…
