007skaty Holograms and Wavefront Reconstruction
Split the laser to capture the phase, rebuilding the wavefront in space.
007skaty Soviet physicist Yuri Denisyuk recorded interference patterns inside thick photographic emulsion, bringing reflection holography to the general public.
BETA
007skaty Drag and layer colorful 3D splats to learn how computers reconstruct holographic scenes.
Fun Fact
Laser power: True holograms cannot be captured without lasers because ordinary light waves are too messy and chaotic.
Glossary
hologram (noun)
A three-dimensional image formed by the interference of light beams from a laser or other coherent source. These recordings are commonly utilized as security features on credit cards, banknotes, and passports.
