AI Article Synopsis

  • A new fast calculation method for computer-generated holograms is introduced, focusing on a patch model that utilizes the point-based method.
  • This method improves calculation speed by basing the time on the number of patches instead of point light sources, making it efficient for large areas.
  • Tests on a graphics processing unit showed that this novel method is over 8 times faster than traditional point-based methods.

Article Abstract

The point-based method and fast-Fourier-transform-based method are commonly used for calculation methods of computer-generation holograms. This paper proposes a novel fast calculation method for a patch model, which uses the point-based method. The method provides a calculation time that is proportional to the number of patches but not to that of the point light sources. This means that the method is suitable for calculating a wide area covered by patches quickly. Experiments using a graphics processing unit indicated that the proposed method is about 8 times or more faster than the ordinary point-based method.
