Review on digital holography techniques using digital micromirror device

This paper provides an in-depth exploration of holographic methodologies, focusing particularly on digital holography facilitated by Digital Micromirror Devices (DMD). We thoroughly examine the theoretical foundations of holographic capture and reconstruction, emphasizing the role of DMDs in these processes. The study covers the principles of diffraction that govern the interaction between light waves and DMDs, alongside a detailed look at the structure, operating principles, and holography-relevant properties of DMDs. We discuss various approaches to creating holographic displays, addressing the inherent challenges and proposing potential solutions. The paper further explores computational strategies for crafting holograms for 3D displays using DMDs and examines multiple advanced techniques for holographic image reconstruction. Our findings highlight the distinctive advantages of DMDs in holography, such as their fast switching speeds, increased angular separation between reconstructed and incident beams, and finer mirror pitch, all contributing to superior hologram quality. We conclude that DMD-based systems hold significant promise for advancing the field of holographic displays.
