Abstract

The division of focal plane (DoFP) polarimeters gradually become the mainstream technology in the field of polarization imaging. In this paper, the multispectral DoFP polarimeter is implemented using commercial off-the-shelf technology, and an information model of which is established. Due to the unavoidable nonuniformity of the response of different pixels and the need to ensure data accuracy in quantitative applications, we describe the calibration method to complete the system-level polarimetric calibration of the multispectral DoFP polarimeter. Finally, the validity of the calibration method was verified by testing in the laboratory with high-precision polarizing glass piles with an adjustable polarization degree.
