• To achieve high-quality 3D holographic image reconstruction.

Main Methods:

• Development of a novel optical system integrated with advanced calculation algorithms.
• Implementation of a projector-type architecture for holographic fringe pattern display.
• Experimental validation of the system's performance and visual field angle.

Main Results:

• The proposed system achieved a visual field angle three times larger than standard electro-holographic displays.
• Demonstrated capability for displaying binocular, full-color, high-resolution 3D reconstructed images.
• Confirmed accurate depth presentation in the reconstructed holographic images.

Conclusions:

• The projector-type electro-holographic display effectively overcomes the narrow visual field angle limitation.
• The system offers a promising solution for advanced 3D holographic imaging with improved visual experience.
• This technology advances the field of electro-holography towards more practical and immersive applications.
