PSF: Polarized Spiral Point Spread Function for Single-Shot 3D Sensing
Bhargav Ghanekar, Vishwanath Saragadam, Dushyant Mehra +3
We propose a compact snapshot monocular depth estimation technique that relies on an engineered point spread function (PSF). Traditional approaches used in microscopic super-resolu…
Single-Photon Structured Light
Varun Sundar, Sizhuo Ma, Aswin C. Sankaranarayanan +1
We present a novel structured light technique that uses Single Photon Avalanche Diode (SPAD) arrays to enable 3D scanning at high-frame rates and low-light levels. This technique,…
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…
