摘要

FT lens of a novel type of improving the phase conjugate in holographic data system is provided. FT lens of this type have the isoplanatic patch large unique. Relaxation of assembly tolerance, read / write architecture asymmetric, and which enables compensation for aberrations of the plate which is inclined in the medium.
