Paper Abstract

Two different configurations of the Diffractive Plenoptic Camera (DPC), the DPC and the Intermediate Image (II) DPC, had previously been built and their performances compared. The DPC couples a diffractive optic with plenoptic camera designs that provide snapshot spectral imaging capabilities but produce rendered images with low pixel count and low spatial resolution. The IIDPC, a modified setup of the DPC, was introduced as a system that could improve the spatial resolution. The IIDPC improved resolution over a narrow centralized spectral range, while the DPC had sustained resolution over a larger spectral range. Further study of both systems was desired to understand what the limiting factor in their performance was. Frequency analysis of both systems was carried out to determine the limiting component of each system. The limiting optic in both systems was determined to be the Microlens Array (MLA).
