We show that fanning noise in lithium niobate crystals can have a deleterious effect on holographic storage in configurations in which the c axis and the grating wave vector coincide, for both ordinary and extraordinary light polarizations. We then demonstrate that this noise is drastically reduced when the c axis is perpendicular to the grating wave vector. Images have been fixed and read out for many hours at high intensity levels, demonstrating long-term storage and good-quality image recall.
我们表明，对于寻常光和非寻常光偏振，在铌酸锂晶体中，当c轴与光栅波矢重合的配置下，扇形噪声会对全息存储产生有害影响。然后我们证明，当c轴垂直于光栅波矢时，这种噪声会大幅降低。图像已在高强度水平下固定并读出数小时，证明了长期存储和高质量的图像再现。
