Excerpt

Whereas conventional analog holography (AH) entails physical re-illumination of the hologram of the object with a reading beam and finding the 3D real or virtual image, digital holography (DH) is a numerical procedure that simulates Fresnel diffraction of light from the re-illuminated hologram on a computer and numerically determines the images, which can be displayed on a computer screen.
