In an undated brief writeup, Venture Radar posts that Sparks Polarimetry LLC has developed an innovative spectropolarimeter that is sensitive to circular polarization. The polarimeter is defined as small and robust, with no moving parts, is simple in concept and extremely well-suited to space. Full polarimetric information is encoded on a single data frame hence polarimetry of transient, fast moving or variable targets can be acquired. No other apparent digital footprint
