Abstract

Advancements in the observation of light polarization using innovative lensless imaging devices are widely explored in the scientific field. This Master's thesis studies the detection of linear light polarization using a lensless imaging device known as the DiffuserCam. Light polarization detection holds significant promise across scientific domains, including biomedical imaging, materials mechanics, and remote sensing. By integrating linear polarizers into the DiffuserCam setup, this research aims to capture polarization data in a single instance. Thereby, it increases the efficiency and precision of polarization measurements while providing a low-cost, accessible, and compact system, unlike the current state-of-the-art. The study focuses on the reproduction of the DiffuserCam and the computation of Stokes parameters to detect and determine the orientation of linearly polarized light. The results underline the potential of the DiffuserCam in various applications involving the detection of light polarization due to its light and small design, accessible materials, and adaptability. Future directions include exploring advanced computational techniques for image reconstruction and error mitigation, as well as extending the system's capabilities to detect circular polarization, aiming to offer a full-stokes polarization lensless imaging system that is easily replicable and scalable.
