We investigate the application of 2-dimensional Principal Component Analysis (2D PCA) to the problem of removal of polarization fringes from spectro-polarimetric data sets.

Measured performance of shadow-cast coated gratings for spectro-polarimetric applications

Measured vector efficiency of an echelle grating
Wednesday, August 1, 2018

Roberto Casini et al report on the measurements of the vector efficiency of a reflective blazed diffraction grating, which was specially coated in order to reduce the level of polarization in the diffracted light.
