Abstract
Provided is a hologram generation method including receiving three-dimensional (3D) data information, determining a first projection position onto which the 3D data information is projected on a hologram plane corresponding to a first spatial light modulator (SLM), and a second projection position onto which the 3D data information is projected on a hologram plane corresponding to a second SLM, generating a first Fresnel zone plate (FZP) pattern corresponding to the first projection position, and determining the first FZP pattern to be an FZP pattern corresponding to the second projection position.
Claims15
A hologram generation method comprising:
- receiving three-dimensional (3D) data information;
- determining a first projection position onto which the 3D data information is projected on a hologram plane corresponding to a first spatial light modulator (SLM), and a second projection position onto which the 3D data information is projected on a hologram plane corresponding to a second SLM;
- generating a first Fresnel zone plate (FZP) pattern corresponding to the first projection position;
- and
- reusing the first FZP pattern as a second FZP pattern for the second projection position, when the first FZP pattern is determined to be the second FZP pattern corresponding to the second projection position.
A hologram generation apparatus comprising:
- an inputter configured to receive three-dimensional (3D) data information;
- a plane projector configured to determine a first projection position onto which the 3D data information is projected on a first spatial light modulator (SLM) and a second projection position onto which the 3D data information is projected on a second SLM;
- and
- a Fresnel zone plate (FZP) pattern generator configured to generate a first FZP pattern corresponding to the first projection position, and reusing the first FZP pattern as a second FZP pattern for the second projection position, when the first FZP pattern is determined to be the second FZP pattern corresponding to the second projection position.
A hologram generation method comprising:
- receiving three-dimensional (3D) data information;
- calculating 3D data visualized on a hologram plane corresponding to each spatial light modulator (SLM) for indicating a corresponding viewpoint;
- calculating a projection position of the visualized 3D data on the hologram plane;
- and
- reusing a first Fresnel zone plate (FZP) pattern of a hologram plane of a pre-processed reference viewpoint as a second FZP pattern for a hologram plane of a non-processed viewpoint, when the first Fresnel zone plate (FZP) pattern of a hologram plane of a pre-processed reference viewpoint is determined to be the second Fresnel zone plate (FZP) pattern of a hologram plane of a non-processed viewpoint.
