Abstract:
1. A method for using a plurality of physical liquid crystal layers in producing an output light field corresponding to a three-dimensional image, the method comprising: determining a desired brightness for a first ray and a desired brightness for a second ray in the output light field; controlling the light output from each of a first point on a first physical liquid crystal layer, a second point on a second physical liquid crystal layer, and a third point on a third physical liquid crystal layer so that the light output from the third point on the third physical liquid crystal layer provides the desired brightness of the first ray, wherein the second physical liquid crystal layer is located between the first and third physical liquid crystal layers; and controlling the light output from each of a fourth point on the first physical liquid crystal layer, the second point on the second physical liquid crystal layer, and a fifth point on the third physical liquid crystal layer so that the light output from the fifth point on the third physical liquid crystal layer provides the desired brightness of the second ray, wherein the desired brightness of the first ray is provided simultaneously with the desired brightness of the second ray.
