Abstract

In this report, we experiment on the two-dimensional image reading and writing in the photorefractive nondestructive memory with BaTiO3 crystal. The great extension of the reading time is archived by use of the grating maintenance technique with optical feedback. By calculating the temporal property of the output beam intensity and the index grating amplitude under the incident conditions of the conventional readout technique and our readout technique, we estimate the feedback rate and the coupling strength for high output generating efficiency. We experiment on the two-dimensional image reading and writing with BaTiO3 crystal, and succeed at over 20 minutes reading without image degradation.
