The wide angle spectrum characteristic of polarization interference filter (PIF) is key to the design and manufacture.In order to carry out the real simulation of PIF,the extended 2×2 Jones matrix used for the analysis of angle property of PIF is proposed.This extended 2×2 Jones matrix is more simple and accurate than conventional mathods.
