摘要
The imaging polarimeter is an important tool to measure polarization properties to reconstruct solar magnetic field in solar observation, to discriminate between benign and malignant moles in the living human eye, and so on. In single-pass imaging polarimetry, the intensity scintillation induced by the source's instability or the seeing during the signals obtaining period will induce severe measurement error. Double-pass imaging polarimetry can significantly decrease this influence. In this paper, we have analyzed the measurement error induced by the intensity scintillation for single-pass and double-pass imaging polarimetries. And the simulation and experiment are presented. Their results are coincident with each other.
