摘要
A holographic display apparatus is provided. The holographic display apparatus includes a spatial light modulator configured to diffract light emitted from an incident light source with a shape corresponding to a computer generated hologram (CGH) pattern to generate an image signal, a filtering optical system configured to filter the image signal to select a first signal component among signal components included in the image signal, a first formation optical system configured to form a focus plane with a smaller size than the first image plane on a surface of a mirror via focus on the first image plane based on the first signal component, and a focus scanner configured to form a beam in a direction of 360 degrees based on a tilting angle of the mirror and rotation of the mirror.
