| Summary: | The rapid technology advancement in holography have brought our fantasy alive. Holography is the future of photography and conventional film, the three-Dimension (3D) creates new possibilities each day. A 3D hologram projects images, videos and animated programs in 3-dimensional space, this means that the displayed 3D hologram is visible from all axes, namely the X, Y and Z axis. There are three types of holograms: Reflection Holograms, Transmission Holograms and Hybrid Holograms. The most competent type of holograms is the Hybrid Holograms, where the Computer-Generated Holograms and Spatial Light Modulator are operated concurrently to reconstruct a 2D and 3D holographic image. This report will explain in detail regarding the implementation of a feedback-based phase modulation method to obtain a customized 2D and 3D holographic image by exploring the various iterative optimization algorithms. The description of the three types of iterative optimized algorithms will be discussed with the help of simulation in the report. The analysis of the simulation and experimental results will be presented in the later part of the report. Matlab will be used to compute the algorithms to generate the required results. |
