Passive Micron-scale Time-of-Flight with Sunlight Interferometry
Alankar Kotwal, Anat Levin, Ioannis Gkioulekas
We introduce an interferometric technique for passive time-of-flight imaging and depth sensing at micrometer axial resolutions. Our technique uses a full-field Michelson interferom…
Swept-Angle Synthetic Wavelength Interferometry
Alankar Kotwal, Anat Levin, Ioannis Gkioulekas
We present a new imaging technique, swept-angle synthetic wavelength interferometry, for full-field micron-scale 3D sensing. As in conventional synthetic wavelength interferometry,…
Enhancing Speckle Statistics for Imaging inside Scattering Media
Wei-Yu Chen, Matthew O'Toole, Aswin C. Sankaranarayanan +1
We exploit memory effect speckle correlations for the imaging of incoherent linear (single-photon) fluorescent sources behind scattering tissue. While memory effect-based imaging t…
