提出了一种从单离轴数字全息图中提取数字参考波精确参数的新方法。该方法使Rd更接近全息图采集实验中的参考波(R)。推导了离轴数字全息图与数字参考波或数字共轭参考波相乘的光谱表达式，研究了离轴数字全息图的光谱特性。结果表明，Rd的参数与重叠谱图中心选定区域的大小有关。当Rd = R时，所选择的重叠区域的大小最小。因此，可以通过找到所选重叠区域的最小值来确定Rd的参数。仿真结果验证了该方法的有效性。
A novel digital method to extract the precise parameters of digital reference wave (Rd) from a single off-axis digital hologram is proposed. The method makes the Rd closer to the reference wave (R) used in experiment of hologram acquisition. The spectrum expression of off-axis digital hologram multiplied with a digital reference wave or a digital conjugate reference wave is derived for the study of the spectrum characteristics. It is shown that the parameters of the Rd are related to the size of the selected area in the center of the overlapped spectrogram. When Rd = R, the size of selected overlapped area is minimum. Thus, the parameters of the Rd can be determined by finding the minimum of the selected overlapped area. Some simulation results are given to validate the proposed method.
