光散射介质的退偏振功率和偏振熵:实验与理论

Depolarizing power and polarization entropy of light scattering media: experiment and theory

Graciana Puentes, Dirk Voigt, Andrea Aiello, J. P. Woerdman

摘要:

实验研究了一类散射光学介质的退偏功率和偏振熵。通过偏振层析成像,这些量是从一个有效的穆勒矩阵,这是通过我们使用的多模式检测方案的正式描述介绍,最近提出的Aiello和Woerdman(arXiv:quant-ph/0407234)。这一建议强调了一个有趣的普遍性,在经典以及量子光散射的偏振方面,在这方面的贡献,我们证明实验,这种普遍性是服从一个令人惊讶的广泛类去极化介质。这反过来又为实验者提供了任何散射介质的偏振特性的有用表征,以及测量数据有效性的通用标准。

英文摘要:

We experimentally investigate the depolarizing power and the polarization entropy of a broad class of scattering optical media. By means of polarization tomography, these quantities are derived from an effective Mueller matrix, which is introduced through a formal description of the multi-mode detection scheme we use, as recently proposed by Aiello and Woerdman (arXiv:quant-ph/0407234). This proposal emphasized an intriguing universality in the polarization aspects of classical as well as quantum light scattering; in this contribution we demonstrate experimentally that this universality is obeyed by a surprisingly wide class of depolarizing media. This, in turn, provides the experimentalist with a useful characterization of the polarization properties of any scattering media, as well as a universal criterion for the validity of the measured data.
