本文基于麦克斯韦方程组和介电张量，从电动力学角度解释了二色性介导的偏振感知机制，并统一描述了海丁格刷等多种内视现象。
AI 中文摘要
人类通过黄斑亨勒纤维层产生的内视现象感知光的偏振，在该纤维层中，叶黄素色素在放射状纤维上优先吸收。仅从该层的复介电张量出发，采用Berreman $4\times4$形式的麦克斯韦方程组即可得到其穆勒矩阵，该矩阵由四个标量$\{A,B,C,D\}$决定。其强度通道仅依赖于二色性对$A$和$B$，这两者将感知固定在最大对比度$|B|/A\approx0.05$处。一个关系式生成了整个二色性介导的感知族：均匀场下的海丁格刷，其暗臂垂直于$\mathbf{E}$矢量；空间变化场下的破碎刷；以及矢量涡旋照明下的$N$重刷。
英文摘要
Humans see the polarization of light through entoptic percepts arising from the macula's Henle fiber layer, where xanthophyll pigments absorb preferentially across the radiating fibers. From the layer's complex dielectric tensor alone, Maxwell's equations in Berreman $4\times4$ form yield its Mueller matrix, set by four scalars $\{A,B,C,D\}$. Its intensity channel depends only on the dichroic pair $A$ and $B$, which fix the percepts at a maximum contrast $|B|/A\approx0.05$. One relation generates the whole dichroism-mediated family: Haidinger's brushes under a uniform field, their dark arms perpendicular to the $\mathbf{E}$-vector; fractured brushes under spatially varying fields; and $N$-fold brushes under vector-vortex illumination.
