Abstract： Division of focal plane polarization camera is a widely used integrated polarization imaging system. Crostalk between pixels of the micro-polarizer arrys （MPAs） is the unique interference factor in such system，and its crosstalk light intensity varies with the polarization characteristics ofthe incident light， bringing errors to the measurement of the target's polarization information.This paper reviews the development of polarization crosstalk models and summarizes allthe factors affecting crosstalk identified in relevant researchs.Taking sensor parameters and optical system parameters as key factors， this paper discusses the cause-effect model of crosstalk in cameras and its relation to temporal noise. It analyzes the results of parameter changes caused by crosstalk， primarily summarizing the crosstalk's factor correlation， experimental repeatability， eror randomness and parameter calibration. Finally， this paper prospects the future development trendsofcrosstalk models.

Key Words： polarization imaging; division of focal plane （DoFP） camera; pixel crosstalk; polarization parameters calibration
