Abstract

One of the problems that affects the practical use of holographic memory is deterioration of the reproduced images due to aberration in the optical system. The medium used in holographic memory systems must be interchangeable, and hence, it is necessary to clarify the influence of aberration in the optical system on the signal quality and perform aberration correction for drive compatibility. In this study, aberration is introduced in the reference light beam during image reproduction, and the deterioration of the reproduced image signal is examined.
