Mantis Shrimp Eyes Could Show Way To Better DVD And CD players

In ScienceDaily, it is reported that thhe mantis shrimps in the study are found on the Great Barrier Reef in Australia and have the most complex vision systems known to science. They can see in twelve colours (humans see in only three) and can distinguish between different forms of polarized light.

Special light-sensitive cells in mantis shrimp eyes act as quarter-wave plates -- which can rotate the plane of the oscillations (the polarization) of a light wave as it travels through it. This capability makes it possible for mantis shrimps to convert linearly polarized light to circularly polarized light and vice versa.

Dr Nicholas Roberts, lead author of the Nature Photonics paper said: "Our work reveals for the first time the unique design and mechanism of the quarter-wave plate in the mantis shrimp's eye. It really is exceptional - out-performing anything we humans have so far been able to create."

And how did this evolve through only natural processes? Given enough time anything can happen?
