This MATLAB-based program implements computer-generated hologram creation and reconstruction, featuring interference pattern simulation, digital encoding algorithms, and diffraction-based 3D image reproduction.
This technique enables rapid hologram reconstruction through a single Fast Fourier Transform (FFT) operation, suitable for both standard hologram reproduction and holographic interferogram reconstruction with optimized computational efficiency.
Description on MATLAB implementation for information hiding in halftone-encoded computer-generated holograms: The main algorithm implementation is CGHwatermark; phase retrieval function is phaseSL; complex wavefront recording function with known amplitude and phase is Hologen; halftone encoding function is AMhalftone; watermark extraction directly uses MATLAB's built-in FFT2 function. The main program's function call sequence is: Input host information and watermark → phaseSL → Hologen → AMhalftone (embedding completion) → FFT2 (watermark extraction). Results are saved in holo&mark folder.
