摘要

我们开发了一种基于两个统计上独立的斑点图案的场基相加的双镜头技术，用于通过散射层恢复输入极化。该技术从理论上提出，并通过数值和实验证明，通过将参考斑点图案的线性偏振方向调整为相对于 x 轴的 0° 和 45°，可以通过测量叠加斑点图案的偏振程度来实现穿过散射层的物体光束的偏振恢复。该技术可广泛应用于偏振传感和生物医学成像领域。

Dual-shot approach for polarization retrieval through a scattering medium

A dual-shot technique based on the field basis addition of two statistically independent speckle patterns is developed to recover an input polarization through a scattering layer. It is proposed theoretically, and demonstrated both numerically and experimentally that by tuning the linear polarization orientation of the reference speckle pattern to 0° and 45° w.r.t. the x-axis, polarization retrieval of an object beam through a scattering layer can be achieved by measuring the degree of polarization of the superposed speckle pattern. The proposed technique can have a wide range of applications in polarization sensing and biomedical imaging.

期刊介绍： Journal of Optics publishes new experimental and theoretical research across all areas of pure and applied optics, both modern and classical. Research areas are categorised as: Nanophotonics and plasmonics Metamaterials and structured photonic materials Quantum photonics Biophotonics Light-matter interactions Nonlinear and ultrafast optics Propagation, diffraction and scattering Optical communication Integrated optics Photovoltaics and energy harvesting We discourage incremental advances, purely numerical simulations without any validation, or research without a strong optics advance, e.g. computer algorithms applied to optical and imaging processes, equipment designs or material fabrication.
