This Letter describes a Stokes vector measurement method based on a snapshot interferometric common-path spectropolarimeter. The proposed scheme, which employs an interferometric polarization-modulation module, can extract the spectral polarimetric parameters Ψ(k) and Δ(k) of a transmissive anisotropic object by which an accurate Stokes vector can be calculated in the spectral domain. It is inherently strongly robust to the object 3D pose variation, since it is designed distinctly so that the measured object can be placed outside of the interferometric module. Experiments are conducted to verify the feasibility of the proposed system. The proposed snapshot scheme enables us to extract the spectral Stokes vector of a transmissive anisotropic object within tens of msec with high accuracy.
本文描述了一种基于快照干涉共光路光谱偏振计的斯托克斯矢量测量方法。所提出的方案采用干涉偏振调制模块，可以提取透射各向异性物体的光谱偏振参数Ψ(k)和Δ(k)，通过这些参数可以在光谱域中计算出精确的斯托克斯矢量。由于其独特的设计，使得被测物体可以放置在干涉模块外部，因此该方案对物体的三维姿态变化具有很强的固有鲁棒性。进行了实验以验证所提出系统的可行性。所提出的快照方案使我们能够在几十毫秒内高精度地提取透射各向异性物体的光谱斯托克斯矢量。
