  In this paper, we explore the possibility of measuring the complete
polarizations of cosmic photons $\gamma$ and the polarizations of cosmic
electrons $e^{-}$ and positrons $e^{+}$. Our innovative Vector Meson
Photo-production induced polarimetry enables people to measure the circular
plarization compoent of a $GeV$ $\gamma$ and to improve its linear polarization
measurement, and thus enables people to measure the polarization of $GeV$
$e^{+}/e^{-}$ for the first time. We calculate the production process of
$\pi^{+}\pi^{-}$ by a generally polarized photon near nucleon's field in a
generalized VPD-SDMEs Factorization with the fitted experimental data, so that
it's partially model-independent. We also propose the observables and approach
to measure their polarizations based on our calculations. Our new polarimetry
of high-energy cosmic $\gamma,e^{+},e^{-}$ will open a new window to reveal the
mysteries and solve the puzzles of BSM new physics in particle physics and
cosmology.
