DragonflyPol leverages Dragonfly's modular, multi-lens architecture to obtain simultaneous measurements in four linear polarization orientations ($0^\\circ$, $45^\\circ$, $90^\\circ$, and $135^\\circ$) across a $\\sim5\\,deg^2$ field of view, distributed across 44 polarized lens--detector units. Four additional units serve as unpolarized reference channels. We describe a broad range of science goals enabled by this capability, including magnetic field mapping and tomography, dust","authors_text":"Deborah Lokhorst, Hiroshi Akitaya, Jaeyeon Kim, Koji S.
