Reconstruction of Three-Dimensional Fresnel Holograms

This code implements the reconstruction of three-dimensional Fresnel holograms. A three-dimensional Fresnel hologram is an optical hologram capable of reconstructing images of real objects in three-dimensional space. The hologram generation process involves complex optical techniques and computer simulations, utilizing numerical propagation algorithms based on Fresnel diffraction theory. The reconstruction code likely implements key functions such as wavefront propagation calculations, phase retrieval methods, and spatial light modulator (SLM) parameter configurations. However, the development process presents significant challenges due to the intricate nature of holographic computations, including precision issues in Fourier optics transformations and phase unwrapping algorithms. While certain errors in the numerical implementation remain under investigation, this research holds substantial importance for advancing optical computing, digital holography, and computational imaging technologies.
