Wavefront Reconstruction Dynamics

Wavefront reconstruction is the physical hallmark of holography. When a physical or digital hologram is illuminated by a beam matching its original recording reference, the light waves undergo a transformative physical diffraction. This process regenerates the precise spatial envelope of the captured subject.

According to Huygens' principle, each tiny point within a diffracted wavefront acts as a secondary source of spherical light waves. As the light passes through the microscopic slits of the holographic fringe pattern, the constructive and destructive interference of these spherical waves recreates the original wavefront.

This physical reconstruction means that the floating graphic behaves identically to a real physical object. Viewers can adjust their posture or focus their eyes on different depth levels, perceiving true volumetric depth naturally. Understanding this dynamic wave reconstruction is essential for designing high-fidelity spatial arrays.
