Intercomparison of the LASCO-C2, SECCHI-COR1, SECCHI-COR2, and Mk4 Coronagraphs
(Springer, 2012-09)
In order to assess the reliability and consistency of white-light coronagraph measurements, we report on quantitative comparisons between polarized brightness [pB] and total brightness [B] images taken by the following ...
Space-qualified liquid-crystal variable retarders for wide-field-of-view coronagraphs
(SPIE-INT SOC OPTICAL ENGINEERING, 2011-01-01)
Liquid-crystal variable retarders (LCVRs) are an emergent technology for space-based polarimeters, following its success as polarization modulators in ground-based polarimeters and ellipsometers. Wide-field double nematic ...
