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.
本文介绍了利用偏振相移数字全息术进行模式识别。通过全息术，可以获得三维（3D）或二维相位物体两个正交偏振之间的振幅分布和相位差分布。这些信息包含了物体的复振幅和偏振特性，可用于提高物体识别的辨别能力。给出了实验结果以证明这一想法。据我们所知，这是关于使用数字全息术对物体进行三维偏振识别的首次报道。
