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.
