Patent of the Month

In November 2022’s edition of the IHMA patent newsletter more than 100 patents are listed, including Japan telecoms service provider KDDI’s patent titled ‘Computer Composite Hologram generation apparatus, method and programme’. The purpose of the patent is to reduce the memory size required to generate a hologram at high speed without substantially degrading the image quality of the hologram.

A 3D model places a 3D object in virtual space. Specific elemental holograms are selected from the full array of elemental holograms The object point light source integrates light sources having the same three-dimensional coordinates from different element holograms into a common point.

The object point light source is used in the light wave propagation calculation with element holograms that are not selected. The computer calculates the light wave propagation from each point light source to each corresponding elemental hologram surface.
