Abstract

A display system employs an algorithm for generating holograms for a wedged waveguide panel, the wedged waveguide fit for that algorithm and apparatus for projecting holograms in the wedge waveguide. The display system includes a holographic projection system 12 and wedge shape waveguide panel 11. The holographic projection system projects holograms, kinoforms with special calculation, into the waveguide. After propagation, they will be replayed as the target images on the screen. The algorithm, named inverse wedge transform and employing a Fourier transform, is use to calculate and compensate the distortion caused by light injecting into the wedge interface. A wedge transform algorithm is used to calculate how waves propagate in the waveguide.
