Polarimeter by rotating polarizer is one of the well-known and classic division time polarimeter (DoTP). It generally acknowledged that this kind consuming for each measurement although it has simple, accurate compact performances. In paper we present a time-integration using continuous polarizer. The basic principle corresponding mathematical expressions are derived. Numeric analysis experiments also made in paper. Experimental results validate precision feasibility proposed imaging polarization state retrieve theory. frame-frequency image 80fps which limited mainly speed photodetector our experiments, its maximum can achieve over 270fps theory some special applications. That may give new attractive prospects life.
