In this article, we consider the design of monocular multiview optical systems that form optical splitting trees, where the optical path topology takes the shape of a tree because of recursive beam splitting. Designing optical splitting trees is challenging when it requires many views with specific spectral properties. We introduce a manual design paradigm for optical splitting trees and a computer-assisted design tool to create efficient splitting-tree cameras. The tool accepts as input a…

Computational plenoptic imaging
TLDR
The state of the art in joint optical modulation and computation reconstruction for acquisition of high-dynamic-range imagery and spectral information is discussed, and how much of this visual information is irreversibly lost in conventional image acquisition is shown.
Computational videography with a single axis, multi-parameter lens camera
