3d display apparatus and method based on low-coherence light source

A method for displaying a three-dimensional (3D) image, comprising:

• generating two-dimensional (2D) amplitude information using a self-emissive low-coherence light source and displaying the 2D amplitude information on a first modulation panel;
• delivering the 2D amplitude information output from the first modulation panel to a second modulation panel;
• and
• phase-modulating the 2D amplitude information in the second modulation panel, thereby converting the 2D amplitude information into voxels in a 3D space.

A three-dimensional (3D) display apparatus based on a low-coherence light source, comprising:

• a first modulation panel for generating and displaying two-dimensional (2D) amplitude information using a self-emissive low-coherence light source;
• a second modulation panel for converting the 2D amplitude information of the first modulation panel into voxels in a 3D space by modulating the 2D amplitude information into phase information;
• and
• an optical system for enlarging or reducing 2D amplitude information output of the first modulation panel using a lens and delivering the enlarged or reduced 2D amplitude information to the second modulation panel,
• wherein 2D amplitude information of each pixel of the first modulation panel is mapped to a macro pixel including N×N pixels of the second modulation panel and is then processed.
