sampling for both spatial and angular dimensions. Single-shot light field cameras
sacrifice spatial resolution to sample angular viewpoints, typically by multiplexing
incoming rays onto a 2D sensor array. While this resolution can be recovered using
compressive sensing, these iterative solutions are slow in processing a light field. We
present a deep learning approach using a new, two branch network architecture,
consisting jointly of an autoencoder and a 4D CNN, to recover a high resolution
4D light field from a single coded 2D image. This network decreases reconstruction
time significantly while achieving average PSNR values of 26-32 dB on a variety of
light fields. In particular, reconstruction time is decreased from 35 minutes to 6.7
minutes as compared to the dictionary method for equivalent visual quality. These
reconstructions are performed at small sampling/compression ratios as low as 8%,
allowing for cheaper coded light field cameras. We test our network reconstructions
on synthetic light fields, simulated coded measurements of real light fields captured
from a Lytro Illum camera, and real coded images from a custom CMOS diffractive
light field camera. The combination of compressive light field capture with deep
learning allows the potential for real-time light field video acquisition systems in the
future.
Our work explores a fascinating experiment in physics and science, the Double-Slit Experiment. We cover the mystery of this experiment, representing the wave and particle nature of photons, electrons, and quantum elements. We recount the history of quantum physics, an unknown field for most people due to its detachment from the world we see. Finally, we explore the capability of the human eye to detect light in its quantum state, closing the gap between us and quantum physics.

Wave-particle duality is concerned with the dual nature of light. Specifically, the particle and wave nature of light. The particle nature of light is the little packages of photons that make up light, and the wave nature of light is the wave pattern that light follows. An example of a way that light behaves like a particle is that it can’t go through walls like sound can. Light also can behave like a wave when we observe the interference pattern of light. This dual nature of light is important because nothing else known in the universe behaves and can be described in the way that light is. Getting to the consensus that light is both a particle and a wave has been a heated debate for decades, and to this day imagining what light truly is, is not humanly possible due to our lack of experience with a wave-particle nature. This thesis explores the history of the debates on the nature of light, and how the modern view was accomplished.
Architecture has the potential to promote introspection when collaborating with natural elements that invoke observation of the natural world. Through a distinct coalition with natural light, materiality, and deliberate design, a space can transcend the user into a new realm that bridges the natural and the built environment. Suppose architecture is organized systemically to solely mediate the user and the natural world, offering opportunities for observation. In that case, it may catalyze the user to access their internal processes and sensations of the world around them. The abstract philosophies of Transcendentalism as a literary form can be translated through architecture as a physical form. Examining proponents of Transcendentalism and its emphasis on nature and individualism can establish a precedent for architecture as a tool for introspection. The works of light Artist James Turrell and the role of experiential architecture further demonstrate how natural light can organically supplement the overall effect of physical space. A synthesis of these underlying paradigms can produce architecture that exceeds its physical form and built environment and, instead, enters a metaphysical realm. This thesis seeks to demonstrate that if programs are designed to be associated with nature, there is an architectural manipulation through the senses and the natural environment, possibly providing opportunities for humans to achieve an elevated sense of introspection. This particular exploration of architecture can further supplement existing design practices and philosophical theories as it joins with nature, potentially promoting an introspective impact on the user’s psyche and cognizance.
