Area of Science:

• Optics and Photonics
• Information Storage Technology
• Computational Physics

Background:

• Holographic data storage offers high density potential.
• Efficient readout mechanisms are crucial for high-speed access.
• Understanding component coupling is key to optimizing holographic memory systems.

Purpose of the Study:

• To analyze the relationship between storage plate and detector matrix dimensions in fast holographic mass memory.
• To determine optimal geometric configurations for maximizing data storage capacity and readout speed.
• To establish design parameters for high-capacity holographic data storage.

Main Methods:

• Application of diffraction theory to model holographic memory components.
• Analysis of geometric coupling between the storage plate and detector matrix.
• Calculation of required detector matrix dimensions for a target data capacity.

Main Results:

• Storage plate and detector matrix proportions are strongly coupled in fast holographic mass memory.
• A large detector array is necessary for high-capacity, fast data storage.
• Optimized geometry is achieved when the storage plate and detector matrix are of equal size.
• A square detector matrix with a 1m diagonal extension can support approximately 10^10 bits in an optimally designed system.

Conclusions:

• The physical dimensions of the storage plate and detector matrix are interdependent for optimal holographic memory performance.
• Achieving high data capacities (e.g., 10^10 bits) necessitates large-scale detector arrays.
• Future holographic mass memory designs should prioritize matching storage plate and detector matrix sizes for efficient operation.
