On Plenoptic Multiplexing and Reconstruction
Photography has been striving to capture an ever increasing
amount of visual information in a single image. Digital
sensors, however, are limited to recording a small subset of
the desired information at each pixel. A common approach to
overcoming the limitations of sensing hardware is the optical
multiplexing of high-dimensional data into a photograph. While
this is a well-studied topic for imaging with color filter
arrays, we develop a mathematical framework that generalizes
multiplexed imaging to all dimensions of the plenoptic
function. This framework unifies a wide variety of existing
approaches to analyze and reconstruct multiplexed data in
either the spatial or the frequency domain. We demonstrate
many practical applications of our framework including
high-quality light field reconstruction, the first comparative
noise analysis of light field attenuation masks, and an
analysis of aliasing in multiplexing applications.

Abstract
Planar mirror systems are capable of generating many virtual views, yet their
practical use for multi-view imaging has been hindered by limiting configurations that enable
view decomposition. In this work we lift those restrictions.
