Abstract

For almost 20 years, microgrid polarimetric imaging systems have been built using a $2\times 2$ repeating pattern of polarization analyzers. In this Letter, we show that superior spatial resolution is achieved over this $2\times 2$ case when the analyzers are arranged in a $2\times 4$ repeating pattern. This unconventional result, in which a more distributed sampling pattern results in finer spatial resolution, is also achieved without affecting the conditioning of the polarimetric data-reduction matrix. Proof is provided theoretically and through Stokes image reconstruction of synthesized data.
