Abstract: A holographic optical system and a holographic display method may be efficiently applied when using a spatial light modulator (SLM). A holographic display apparatus includes a spatial light modulator (SLM) configured to reproduce a hologram, and an optical system configured to perform Fourier transform with respect to the hologram of the SLM using a pair of first and second lenses, the first and second lenses being confocal. A Fourier plane which is a display reference image plane is positioned in the same plane space as the second lens.

Abstract: A method and apparatus for correcting a distortion of a holographic display. The method includes tracking a location of a viewing window by tracking a location of a pupil of a user and calculating a central location of the viewing window, generating a wavefront aberration by determining an object point and an image point based on a location of a light source and the central location of the viewing window and using ray tracing, and calculating a complex aberration light field using the generated wavefront aberration. Thus, a quality of a holographically reproduced image in a viewing window-based holographic display may be improved.
