METHOD AND APPARATUS FOR CORRECTING DISTORTION OF 3D HOLOGRAM

摘要

The present invention relates to a three-dimensional hologram distortion correction method and a device for the same. According to the present invention, the three-dimensional hologram distortion correction method includes: a step of generating a two-dimensional hologram cross section by slicing a cross section of a hologram in an optical axis direction; a step of obtaining a clear focused hologram cross section image of the generated two-dimensional hologram cross section using the focusing function of a camera; and a step of analyzing distortion of the obtained hologram cross section image generated by a display optical system. Therefore, the present invention can correct distortion of a three-dimensional hologram independently from the display structure.
