In order to obtain the rule of polarization measurement error caused by the phenomena of convergent light in a polarization camera,based on three dimensional polarization ray tracing calculi,the effect of transmitted polarized intensity parallel to optical axis on the measurement accuracy of polarization degree was studied.Simulation results show that the measured degree of polarization is always less than the real polarization degree due to the convergence of light,and polarization measurement error increases with the convergent angular.It is also indicated that for a certain light convergent state and polarization measurement condition,the larger the polarization degree of incident light,the bigger the polarization measurement error.
