Phase Retrieval from Electric Field Intensity for Wide Angle Optical Fields

Abstract

Abstract:An intensity preserving scalar to vector electric field mapping, in a wave propagation environment, based on a filtering procedure is proposed. In a phase retrieval problem, the proposed mapping outperforms the conventional mapping.

Generation of a polarized optical field from a given scalar field for wide-viewing-angle holographic displays

“…Hence, a viewer that captures the locally paraxial segment of the field actually does not capture the paraxial segment in the global coordinates. and Onural [28,35] when the imaging device is located at an on-axis plane and has no diffraction limitation. = 𝐤 ∕ 𝑘 in the following section.…”

“…Therefore, in this case, both the proposed and the conventional mappings may fail for the scalar wave theory and one should directly deal with the electromagnetic wave theory due to the large values of the captured longitudinal component. As examples for such cases sample holographically reconstructed images have been presented in Kulce and Onural[28,35] when the imaging device is located at an on-axis plane and has no diffraction limitation.…”
