Data related to the crossed test for the polarimetric characterization of prism 1 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.

本数据集对应博士论文《面向航天应用的高性能光谱偏振计研制》研究框架中所用调制器第一棱镜的偏振表征数据，表征波长为515纳米。数据集包含用于提取该楔形棱镜内部相位变化与快轴方位的拟合流程(fit procedure)对应图像。本次公开的测量包含两类工况：样品置于平行线性偏振片之间，以及样品置于正交线性偏振片之间。两类工况下，两块线性偏振片均以1°为步长在0°至360°范围内旋转，每个偏振方位角均记录5幅图像。此外，数据集还提供了暗场图像(dark images)用于噪声评估。每组图像均附带采集阶段相机精确配置参数的元数据(metadata)。
