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.
