What is it about?
We developed a transparent hologram on glass that can reconstruct realistic full-color 3D images while remaining easy to see through. Under normal lighting, the hologram is almost invisible. When illuminated by red, green, and blue light sources from different directions, it creates a floating full-color 3D image while still allowing people to view objects behind the glass.

Why is it important?
Conventional holograms are often visible even when not in use and typically require separate holograms for different colors. Our research addresses both challenges through a scattering-suppressed hologram design and a single-hologram color-multiplexing scheme. This opens new possibilities for transparent display technologies that seamlessly integrate digital information into the physical environment.
Perspectives
Holography offers a unique way to reconstruct realistic 3D scenes in real space. I hope this work contributes to future visual media and display technologies that blend digital information seamlessly with the physical world.
