Perspective Chapter: Recent Developments in Digital Holography Approach Employing Digital Advanced Micromirror Devices

This investigation explores digital holography using digital micromirror devices (DMDs), examining theoretical foundations and practical applications. We delve into the principles of diffraction, the structure and operation of DMDs, and their holography-relevant properties. The study discusses various methods for producing holographic displays, addressing challenges, and suggesting solutions. Computational strategies for creating holograms for 3D exhibitions employing DMDs and advanced approaches for holographic image modernization are explored. Current findings noted the future of DMDs in holography, such as fast switching speeds, enhancing angular separation between both reconstructed and incident beams, as well as finer mirror pitch and involvement in superior hologram high quality. Also, investigate the employ of DMDs in digital holographic interferometry for a real-time show of interferometric fringes. For faster modulation speed, an electrooptic modulator was employed in synchronization with the DMD in an amplitude modulation mode to create grayscale patterns with a frame rate ~ 833 Hz with a display time noted of only 1.2 ms instead of 38.4 ms for time multiplexing, gaining a speed up by a factor of 32. Experimental results demonstrate the feasibility of DMDs for this purpose, opening new applications in the field.
