We will present a novel calibration technique by using of dual rotation polarization components for four detector polarimeter(FDP). An optical setup for calibrating FDP consists of a linear polarizer and a quarter-wave plate in rotating ratio of one to two. The fourier analysis is used to calculate a instrument matrix which associates the polarization state and optical intensity detected by detectors of FDP. Experimental results correspond reasonably well the theoretical values.
