What is a Hologram?
A hologram is a three-dimensional image formed by the interference of light beams from a laser or other coherent light source. Unlike conventional images that are flat, holograms appear to be three-dimensional, allowing viewers to see the object from different angles.
How Do Holograms Work?
Holograms are created by recording the interference pattern of two beams of light on a photosensitive plate or film. When illuminated by another laser beam, the recorded interference pattern recreates the original light waves, producing a three-dimensional image.
Types of Holograms
- Reflection Holograms
- Transmission Holograms
- Embossed Holograms
Applications of Holograms
Holograms have a wide range of applications, including:
- Holographic Displays
- Holographic Security Features on ID Cards and Banknotes
- Holographic Art and Entertainment
- Holographic Medical Imaging
Case Study: Holographic Displays in Retail
In retail, holographic displays are used to create engaging and interactive product presentations. Companies like Adidas and Nike have used holograms to showcase their latest products in a unique and attention-grabbing way.
Statistics on Holograms
According to a report by MarketsandMarkets, the global holographic display market is expected to reach $3.57 billion by 2020, with a compound annual growth rate of 30.23% from 2015 to 2020.
