Zusammenfassung:	A method for polarization-resolved optical fiber Bragg grating (FBG) characterization is reported on. The complete reflectance Jones matrix is measured interferometrically. Required polarization transformers need not be accurate, just to operate reproducibly, because redundant measurements yield pairs of orthogonal polarizations. Local dichroic reflectivity and birefringence of a sampled grating was derived from this data. Knowledge of these quantities should allow improvement of the ultraviolet (UV) illumination process and to effectively correct phase mask errors by longitudinally selective UV light postprocessing.
