3D Hologram Technology
Why in News: Japan has introduced its first new banknotes in twenty years, featuring yen embedded with 3D hologram technology aimed at combating counterfeiting.
About 3D Hologram Technology:
- Definition: It is a virtual three-dimensional image formed through the interference of light beams that replicate real physical objects, maintaining properties like depth and parallax.
- Visibility: Unlike traditional 3D projections, holograms are visible to the naked eye.
- Principle: Utilizes light wave interference and diffraction to capture and reconstruct 3D images of objects.
- Creation Methods: Two main methods exist: computer-generated holograms for augmented reality glasses and physical holograms for optical displays.
- Applications: Widely used in diverse fields such as medicine, military, weather forecasting, virtual reality, digital art, and security.
Role in Preventing Counterfeiting:
- Complexity: The intricate nature of holograms makes them challenging to replicate using conventional methods.
- Security Features: Their unique patterns and properties are difficult to completely mimic, acting as a deterrent to counterfeiters.
- Recognition: Trained personnel can easily identify genuine products by recognizing specific holographic features, aiding in distinguishing them from counterfeit items.
Vampire squid
Why in News: Scientists recently discovered a rare vampire squid, the second known living species, in the deep waters of the South China Sea
About Vampire Squid:
A small (12-inch-long) cephalopod found in deep temperate and tropical seas.
Possesses characteristics of both squid and octopi, occupying its own order in taxonomy (scientific classification).
Habitat:
- Inhabits tropical and subtropical oceans at depths ranging from 300 to 3,000 meters.
- Majority live between 1,500 and 2,500 meters.
- Resides in the oxygen minimum layer of the ocean, where virtually no light penetrates.
Characteristics:
- Has black chromatophores with reddish-brown ones interspersed.
- Unlike other cephalopods, these chromatophores are non-functional due to the loss of muscles needed for rapid color change.
- Shares most features with other octopods and decapods but has adaptations for deep-sea living.
- Equipped with photophores, large circular organs located behind each adult fin and spread over the mantle, funnel, head, and aboral surface.
- Photophores produce luminescent clouds of glowing particles, allowing the squid to glow.
- Possesses proportionally the largest eyes of any animal in the world.
Food Habit: Deep-sea scavengers gravitating toward feces and dead animals.
