For Prelims: About 3D Hologram Technology, How do holograms prevent counterfeiting? |
Why in the news?
Japan issued its first new banknotes in two decades, yen packed with 3D hologram technology to fight counterfeiting.
About 3D Hologram Technology:
- It is a virtual three-dimensional image created by the interference of light beams that reflect real physical objects. Holograms preserve the depth, parallax, and other properties of the original item.
- Unlike conventional 3D projections, holograms can be seen with the naked eye.
- Principle: It uses the principles of interference and diffraction of light waves to record and reconstruct 3D images of objects.
- There are two methods for creating holograms: computer-generated holograms for augmented reality glasses and actual holograms for optical displays.
- Application: It has a wide range of applications in medicine, the military, weather forecasting, virtual reality, digital art and security.
How do holograms prevent counterfeiting?
- Holograms prevent counterfeiting because of their complexity, making them difficult to replicate using traditional methods.
- Holograms’ intricate patterns and properties make them difficult to duplicate completely, which deters counterfeiters.
- Additionally, holograms are designed to be easily recognizable by trained individuals, facilitating quick identification of genuine products versus fake ones.
