Calculation of diffracted optical fields for arbitrary polygons from a primitive polygon.
Application of pseudo-inverse matrix, interpolation, and power spectral density compensation.

Main Results:

The proposed method significantly saves computation time by avoiding per-surface fast Fourier transforms and additional diffusion computations.
Numerical simulations and optical experiments validate the method's effectiveness.
Successful reconstruction of 3D scenes with a solid effect and no depth limitation was achieved.

Conclusions:

The developed polygon-based method offers a substantial improvement in the efficiency of holographic hologram synthesis.
The method provides high-quality 3D reconstruction, overcoming previous depth limitations.
