Data related to the crossed test for the polarimetric characterization of prism 3 of the modulator

This data refers to the polarimetric characterization, at a wavelength of 515 nm, of the first prism of the modulator used in the frame of the PhD thesis "Development of a high-performing spectropolarimeter for space usage". The data set contains images corresponding to the "fit procedure" for retrieving the phase variation and the fast axis orientation inside this wedge. Two types of measurements are presented here: for the specimen situated between aligned linear polarizers and between crossed polarized. For both situations, the two linear polarizers were rotated between 0º and 360º with a step of 1º, and five images were recorded for each orientation. In addition, dark images are provided to assess the noise. Each set of images contains metadata with the precise setup of the camera during the acquisition. The wedge under study was rotated here with 90º around the optical axis to ensure the fixation. The horizontal of the images corresponds then to the vertical of the wedge, and the apex angle is situated at the right.本数据集针对某博士学位论文框架中所用调制器的第一棱镜开展偏振表征，表征波长为515 nm，该论文标题为《面向航天应用的高性能光谱偏振仪研发》。本数据集包含用于反演该楔形棱镜内部相位变化与快轴取向的‘拟合流程’对应图像。本次公开两类测量场景：分别为待测样品置于平行线偏振片之间，以及正交线偏振片之间。两类场景下，两片线偏振片均以1°为步长在0°至360°范围内旋转，且每个偏振片取向均记录5幅图像。此外，数据集还提供暗场图像以用于噪声评估。每一组图像均附带采集阶段相机精确配置的元数据。为确保固定，本次实验中将待测楔形棱镜沿光轴旋转了90°，因此图像的水平方向对应楔形棱镜的竖直方向，且其顶角位于图像右侧。
