Improved polygon-based method for subwavelength pixel pitch computer generated holograms

- An improved polygon-based method for holographic display is proposed.
- The holograms with subwavelength pixel pitch are encoded and displayed.
- The principle of image-plane holography and adjustment of parameters are applied.

An improved polygon-based method is proposed for subwavelength pixel pitch computer generated holograms (CGHs). By employing the basic principle of image-plane holograms, and by optimizing the parameters, objects are reconstructed with high quality from the CGHs whose pixel pitch is smaller than wavelength. It is believed that the proposed method is potentially promising for future large viewing angle holographic 3D displays.
