Shrimp eyes could revolutionise DVD players
University scientists in the UK, US and Australia claim that new research on crustaceans could usher in a new age of DVD and CD players.
Mantis shrimps, from Australia’s Great Barrier Reef, can see colours across virtually the entire spectrum; their eyes performing a similar polarization function to CD and DVD players. Researchers believe that mimicking this function technologically could be groundbreaking. The light-sensitive cells in mantis shrimp eyes change the polarizations of light as it travels through them, although researchers observed that this polarization worked across the whole visible spectrum whilst DVD and CD players are currently only capable of polarizing one colour of light.
Lead author of the Nature Photonics paper, Dr Nicholas Roberts, called the discovery “exceptional”, saying that future technology could exploit similar multi-coloured polarization if developers could “mimic the properties of the cells in the mantis shrimp’s eye”.
