基于耦合波理论并引入波矢簇的概念 ,对体全息存储分维复用的串扰噪声进行了分析。在改变参考光俯仰及偏转角度条件下对全息图的读出图像进行了模拟计算 ,给出了实验结果 ,计算得到了二维串扰强度分布。理论及实验证明 ,在改变读出参考光俯仰角的情况下 ,谱面全息图呈现水平带状读出 ,并且带状图样随偏转角改变而上下移动 Based on the concept of coupled wave theory and the introduction of wave vector tuners, the crosstalk noise of volume holdup multiplexing in volume holography is analyzed. The readout images of the hologram are simulated under the condition of changing the reference light pitch and the deflection angle. The experimental results are given and the two-dimensional crosstalk intensity distribution is calculated. Theoretical and experimental results show that the spectral hologram is read out horizontally and horizontally when the pitch angle of the reference light is read, and the strip pattern moves up and down as the deflection angle changes
