The hologram has fascinated for decades. But what exactly is a hologram, how does it work, and what are its concrete professional uses? This guide answers all these questions.

Definition: what is a hologram?

A hologram is a three-dimensional image created by light interference, giving the illusion of an object floating in space. Unlike a 2D image, it has depth and can be observed from different angles.

How does a hologram work?

Modern holographic systems rely on several technologies:

  • LED fan: LEDs on rotating blades create the illusion of a floating 3D image through persistence of vision
  • Holographic pyramid: reflection of an image on four inclined transparent faces
  • Pepper’s Ghost projection: reflection on a semi-transparent glass used for human holograms
  • Holobox: closed display case creating a 4K high-definition hologram

Types of holograms in 2026

  • Holographic fan: ideal for storefronts, stands and retail activations. Visible in daylight (670 nits).
  • Holobox: closed case for luxury, jewellery, pharmacy.
  • Pyramid: 360° visibility, ideal for showroom presentations.
  • Holographic projection: for large-scale events and spectacular shows.

Professional uses of holograms

  • Retail: shopfront animation, product showcase, traffic generation
  • Events: trade show stands, product launches, conferences
  • Luxury: immersive presentation in flagship boutiques
  • Automotive: showrooms without physical vehicles, 3D configurators
  • Healthcare: medical training, anatomical visualisation
  • Real estate: off-plan sales, immersive virtual tours
