Abstract: Provided is an information encoding method and a holographic memory device which increase the amount of information per page of a holographic memory and reduce the bit error rate to ensure a larger multiplexing number. The holographic memory information encoding method expresses information of signal page data in a holographic memory as a multi-stage data using different resolution by block coding, and superimposes each data on a single page of signal page data. The multi-stage data using different resolution is realized by light amplitude data and phase data. The amplitude data is divided by area through block coding. When n odd-numbered ON bits exist in a divided area of the phase data, a phase of 2?s/n (where n and s are natural numbers) is imparted as s-th phase information to one value of binary data, and the same phase is imparted to the other value of binary data.

Abstract: An embodiment with a dual-stage reflectron is as follows: (1) On the assumption that a reflector has a base potential XA(U) created by uniform electric fields, its design parameters are adjusted so as to cancel the first and second order derivatives at energy E=E0 of a total time of flight T(E), and a second-order focusing position on a central axis at which the potential value becomes zero is determined (Mamyrin solution). (2) A correcting potential XC(U) to be superposed on XA(U), beginning from the second-order focusing position, is calculated so that T(E) of ions reflected in a region deeper than the second-order focusing position will be constant. (3) Voltage values of the reflector electrodes are determined so that a real potential XR(U)=XA(U)+XC(U) is created on the central axis.
