摘要:
Ten thousand data pages, each containing 768x768 pixels, have been stored in a single section of a disk-shaped, iron-doped LiNbO3 crystal using spatioangular multiplexing with a convergent spherical reference beam, leading to an areal density of 33.7bits/mum(2) and a volumetric density of 6.7Gbits/cm(3). The system design considerations for the achievement of the goals ensure the success of the experiment. Customer-designed Fourier transform and imaging optics with short focal length provide tightly confined object beam at the crystal and good image quality in the detector array. An optimized reflection configuration avoids the detrimental scattering from the crystal surface to enter the detector. The images were reconstructed with good fidelity. The signal to noise ratio (SNR) was measured to be 3.6 for the worst-case in the sampled retrieved images, from which, a raw bit error rate of 1.6x10(-4) before error correction could be estimated.
