Homogeneous Codes for Energy-Efficient Illumination and Imaging

A novel framework to maximize energy efficiency by "homogeneous matrix factorization" and a low-power laser-imaging system that performs live direct and indirect imaging, structured light scanning in the presence of strong ambient light, and live imaging of the scene from the perspective of the projector.

Doppler Time-of-Flight Imaging

Doppler Time-of-Flight Imaging is a new paradigm for computational photography. By coding the illumination and processing measured data with custom algorithms, it records velocity maps of a dynamic scene.

Phasor Imaging: A Generalization of Correlation-Based Time-of-Flight Imaging

A novel frequency-domain framework for analyzing light transport in time-of-flight (ToF) imaging that includes fast techniques for ToF-based 3D and direct-global illumination separation in scenes with inter-reflections and volumetric scattering.

Micron-Scale Light Path Decomposition Using Interferometry

This computational imaging system, inspired by optical-coherence tomography, produces light-transport decompositions of small scenes at very high spatial and path-length resolution. It is used to measure and visualize three-dimensional shape, direct and indirect reflection components, properties of scattering, refractive and dispersive characteristics, and birefringent materials.
