Abstract

We demonstrate one-to-one pixel-matching of phase-conjugate digital volume holographic data storage, with data pages as large as a megapel (1024 X 1024 pixels). A self-pumped phase-conjugate mirror in BaTiO₃ is used to provide a phase-conjugate reference beam, which reconstructs the data- bearing object beam from a LiNbO₃:Fe crystal using the 90 degree geometry. The systems tradeoffs of phase-conjugate readout are described, and two methods of generating phase- conjugate reference beams are described and compared.
