Abstract

This paper presents recent advancements in the study of a new concept of space spectropolarimeter. The instrument, based on a triple prismatic structure from a birefringent material, avoids the need of rotating components and may cover the entire Stokes vector for a very broad wavelength band. The analysis of the concept in noise-free conditions has proved its consistency. Further simulations for different geometries of the modulator are presented. The results allow identifying critical values for the main parameters. Moreover, the previous analysis of the instrument in noisy conditions is completed with the impact study of the spectral resolution, dimension of pixels and signal to noise ratio..
