摘    要
本文介绍了一种消除数字全息散斑噪声的方法。利用圆偏振光作为物体照明光,线偏振光作为参考光,通过旋转参考光的偏振方向记录多幅离轴数字全息图,对其强度再现图像平均叠加,从而消除散斑噪声,改善再现像观察效果。我们通过实验和数字统计验证了这种方法的有效性。

Abstract
A novel speckle reduction technique for digital holography is proposed. Multiple off-axis holograms are recorded using a circularly polarized illumination beam and a rotating linearly polarized reference beam. The speckle noise in the reconstructed images is suppressed by averaging these fields. We demonstrate the effectiveness of this technique experimentally and conduct additional statistical evaluation.
