Practical Holography XXXIII: Displays, Materials, and Applications.
A non-interferometric phase retrieval method in the phase-modulated holographic data storage system is proposed. This method can not only avoid phase ambiguity issue with interferometric, but also increase the capacity by reducing media consumption.

Based on the newly developed tensor holography theory, the null reconstruction in orthogonal elliptical polarization holography is reported. In the recording stage, the information is stored in the recording material by two orthogonal elliptical pola

Faithful reconstruction, which is a key phenomenon in optical data storage, is significant in polarization holography and has attracted much attention. It is defined as the reconstructed wave being identical to the signal wave. We design an experimen

For clarifying the mode field characteristics of step and graded index fibers, the Helmholtz's equation and local planar wave approximation are engaged, a novel idea that the eigenfunction of the traveling wave field in radial grade index dielectric
