In this paper, we propose an instrument concept based on a polarization modulation array for the simultaneous measurement of the irradiance, spectrum, and polarization states of the target of interest. Using a group of retarders and polarizers oriented in specific directions, the full set of Stokes parameters can be determined directly without internal moving parts or extensive calculations. The polarization array consists of two retarders and four linear polarizers located at the incident aperture, so that the incident light is divided into four separate modulation channels. To measure the modulated spectra, we include an interference spectrometer based on the Savart polariscope principle in the system and retrieve the polarization spectra by Fourier transform. We apply a tempo-spatially modulation mode in the scheme to extract the multi-dimensional data of each point in the field of view. The system's performance, especially the capability for Stokes spectra measurement, is verified through both computer simulation and laboratory experiments. Possible sources of error are also analyzed.

在本文中，我们提出了一种基于偏振调制阵列的仪器概念，用于同时测量目标的辐照度，光谱和偏振态。使用一组沿特定方向定向的延迟器和偏振器，可以直接确定全套Stokes参数，而无需内部移动部件或进行大量计算。偏振阵列由位于入射孔处的两个延迟器和四个线性偏振器组成，因此入射光被分成四个单独的调制通道。为了测量调制光谱，我们在系统中包括了基于Savart偏振镜原理的干涉光谱仪，并通过傅立叶变换获取了偏振光谱。我们在方案中应用了时空调制模式，以提取视场中每个点的多维数据。该系统的性能，特别是斯托克斯光谱测量的能力，已通过计算机仿真和实验室实验验证。还分析了可能的错误来源。
