The Diffractive Achromat: Full-Spectrum Computational Imaging With Diffractive Optics

Diffractive achromat, a computationally optimized diffractive imaging system in the full visible spectrum, combines optimization in both diffractive optical design and post-capture image reconstruction. In this paper, a prototype diffractive achromat on a 0.5mm ultra-thin glass plate validates the concept.

Practical Multispectral Lighting Reproduction

A practical approach to recording spectrally complex lighting environments and reproducing the lighting on an actor using a sphere with multispectral LED light sources. The method achieves realistic composites that agree closely with photographs, and the technique can be applied to video with dynamic lighting.

Computational Imaging With Multi-Camera Time-of-Flight Systems

This exploration of phased time-of-flight camera arrays develops a reproducible hardware system that allows for exposure times and waveforms of up to three cameras to be synchronized. The method tailors and optimizes the waveforms that drive the temporally coded illumination and on-sensor demodulation codes.

Occluded Imaging With Time-of-Flight Sensors

In this theoretical analysis of the non-line-of-sight "looking around corners" problem, recovery guarantees are provided with a theoretical framework similar to approaches in compressive holography.
