A team of researchers headed by Hayato Watanabe within the Science and Technology Research Laboratories at NHK (Tokyo, Japan) is developing a novel lightfield based 3D TV system. The display is reported as producing an image that has both horizontal and vertical parallax and does so with reduced crosstalk as compared to other lightfield approaches. The system is called Aktina Vision.
An interesting point to note is that the word aktina derives from the Greek word “aktina” meaning ray of light.
