Characterizing Vibrations at the Subaru Telescope for the Subaru Coronagraphic Extreme Adaptive Optics instrument
Julien Lozi, Olivier Guyon, Nemanja Jovanovic +6
Vibrations are a key source of image degradation in ground-based instrumentation, especially for high-contrast imaging instruments. Vibrations reduce the quality of the correction…
Development of a Precise Polarization Modulator for UV Spectropolarimetry
Shin-nosuke Ishikawa, Toshifumi Shimizu, Ryouhei Kano +6
We developed a polarization modulation unit (PMU) to rotate a waveplate continuously in order to observe solar magnetic fields by spectropolarimetry. The non-uniformity of the PMU…
Ly-alpha polarimeter design for CLASP rocket experiment
H. Watanabe, N. Narukage, M. Kubo +7
A sounding-rocket program called the Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) is proposed to be launched in the summer of 2014. CLASP will observe the solar chromosphe…
