研究目的
To propose a new geometric representation of polarization for a general three-dimensional (3D) optical field that can characterize both the degree of polarization (DoP) and the state of polarization (SoP) simultaneously.
研究成果
The proposed geometric representation is a natural way to represent the polarization for a general 3D optical field, capable of illustrating all 3D polarizations quantitatively and qualitatively. It is expected to be useful in applications involving polarization in 3D fields, such as light-matter interactions, microscopy, and 3D polarimetry.
研究不足
The paper does not explicitly mention limitations, but the method's applicability to all 3D optical fields suggests it may require validation across a wide range of scenarios.
1：Experimental Design and Method Selection:
The study is based on the characteristic and eigenvalue decompositions of the 3 × 3 coherency matrix.
2：Sample Selection and Data Sources:
The research uses theoretical models and does not specify particular samples or datasets.
3：List of Experimental Equipment and Materials:
Not specified.
4：Experimental Procedures and Operational Workflow:
The methodology involves decomposing the 3 × 3 coherency matrix into three specific polarized components and constructing a spatial equilateral triangle to represent the DoP.
5：Data Analysis Methods:
The analysis involves calculating the degree of polarization and illustrating the state of polarization through 3D distribution maps of polarization ellipse.
