We perform Mueller matrix imaging (MMI) of diffusely scattering phantoms under sinusoidal irradiance of varying spatial frequency. Quantitative polarimetric sensing via MMI completely characterizes a sample's polarimetric properties, while structured illumination (SI) allows for the control of photon path length. Intralipid phantoms were measured with varying absorption and with varying depth to demonstrate photon path length control for Mueller matrix elements. We observe unpolarized intensity, linear polarization, and circular polarization to depend upon spatial frequency differently. Finally, we measured an chicken skin sample over a bright and dark substrate to further demonstrate the sensitivity of SI-MMI to depth.
我们在空间频率变化的正弦辐照下对漫散射体模进行穆勒矩阵成像（MMI）。通过MMI进行的定量偏振传感能完整地表征样品的偏振特性，而结构化照明（SI）则可控制光子路径长度。使用具有不同吸收率和不同深度的脂血体模进行测量，以证明穆勒矩阵元素的光子路径长度控制。我们观察到非偏振强度、线性偏振和圆偏振对空间频率的依赖方式各不相同。最后，我们在明亮和黑暗的背景上测量了一块鸡皮样本，以进一步证明SI-MMI对深度的敏感性。
