PROBLEM TO BE SOLVED: To provide a holograph system which reduces and avoids introduction of aberrations to the system and, especially, reduces aberrations introduced by a non-picture component like a storage medium. SOLUTION: The storage medium is arranged in an optical path of the system and is rotated around a first axis so that the surface of the storage medium may have non-orthogonal relation to the optical path, and a space optical modulator arranged in the optical path is rotated around a second axis orthogonal t the first axis, and the surface of the space optical modulator has non- orthogonal relation to the optical path. |
