本文提出了偏振相移数字全息用于模式识别的方法。利用全息术，可以得到三维或二维相位物体的两个正交偏振态之间的振幅分布和相位差分布。这些信息包含了目标的复振幅和极化特征，可以用来提高目标识别的分辨能力。实验结果证明了这一想法。据我们所知，这是第一次报告的三维偏振识别的对象，使用数字全息。
Pattern recognition by use of polarimetric phase-shifting digital holography is presented. Using holography, the amplitude distribution and phase difference distribution between two orthogonal polarizations of three-dimensional (3D) or two-dimensional phase objects are obtained. This information contains both complex amplitude and polarimetric characteristics of the object, and it can be used for improving the discrimination capability of object recognition. Experimental results are presented to demonstrate the idea. To the best of our knowledge, this is the first report on 3D polarimetric recognition of objects using digital holography.
