Shrimp eyes could help create a new digital storage format

Mantis shrimp eyes could be the inspiration behind a new way to store and read digital data, say scientists from the University of Bristol who have studied the complex vision system of the stromatopod, which is not really a shrimp.

The mantis shrimp can see far beyond what humans are capable of, including ultraviolet, infrared and circularly polarized light. It also sees in 12 colors, as opposed to the cells in human eyes that only detect three colors.

The researchers have determined the mechanism that the shrimp uses to convert polarized light, which they say works better than man-made polarizing filters because it works across most of the spectrum, while man-made filters usually only work for one wavelength of light.

CD and DVD players use a single wavelength of circularly polarized laser light to read the data on a disc.  New filters developed from the shrimp’s eyes could allow players to use more than one reading laser, allowing more data to be packed onto a single disc.

Why the shrimp need to see in so many colors and different polarizations is unknown, but their eyes could help them find prey (polarized filters are used on cameras to cut through reflections), or signal to each other secretly without predators noticing.
