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…

Neural Implicit Surface Reconstruction using Imaging Sonar

Mohamad Qadri, Michael Kaess, Ioannis Gkioulekas

We present a technique for dense 3D reconstruction of objects using an imaging sonar, also known as forward-looking sonar (FLS). Compared to previous methods that model the scene g…

Fluorescent wavefront shaping using incoherent iterative phase conjugation

Dror Aizik, Ioannis Gkioulekas, Anat Levin

Wavefront shaping correction makes it possible to image fluorescent particles deep inside scattering tissue. This requires determining a correction mask to be placed in both excita…

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,…

Physics-Based Inverse Rendering using Combined Implicit and Explicit Geometries

Guangyan Cai, Kai Yan, Zhao Dong +2

Mathematically representing the shape of an object is a key ingredient for solving inverse rendering problems. Explicit representations like meshes are efficient to render in a dif…
