Abstract: The present invention discloses a non-interferometric, non-iterative complex amplitude reading method and apparatus. The reading method includes the following steps: diffracting a light beam containing amplitude information and phase information to obtain a diffraction pattern with intensity variations; constructing a diffraction intensity-complex amplitude model and training it based on the correlation between the diffraction pattern and amplitude information and phase information, and applying the trained model directly to new diffraction images to obtain amplitude information and phase information. The method can achieve detection of complex amplitude information, including amplitude and phase, from a single diffraction image, improve the stability and accuracy of phase reading results, increase the calculation speed, and simplify the optical system. It is suitable for applications in holographic storage, biomedical image processing, and microscopic imaging, among others.

Abstract: A proposed fabrication technique for a polarization-absorbing wire grid polarizer avoids the need to etch through the multilayer stack of materials to form the grid structure. Initial reflective metal and dielectric buffer layers are patterned and etched in a conventional manner to create the desired grid topology. A small-angle coating process is then used to complete the fabrication process by first coating the top surface of the patterned dielectric with a polarization-absorbing metal. A second coating process is used to cover the created metal coating with a dielectric cladding material. Maintaining a small angle of incidence between the coating source and the wire grid structure ensures that top portions of the grid are suitably covered to create the desired multilayer wire configuration.
