Abstract: Abstract. We propose a divided-aperture imaging technology–based polarization imaging spectrometer, aiming to address the shortcomings of existing missions such as Europa Clipper and Jupiter Icy Moons Explorer. The instrument is capable of acquiring continuous high-spectral… read more here.
