The Stokes imaging polarimeter using a retarder and a polarizer is a direct and conventional method to detect the full Stokes vector of the scene. This method has been widely used for different imaging architectures, such as division of time and division of aperture. System calibration is necessary in polarimetric imagery. The polarization optical elements angular deviation belongs to adjustment error and should be calibration when the device is set up. In this paper we propose a novel method to calibration the angular deviation using Fourier series analysis. A linear polarization state generator including a light source and a linear polarizer is installed before the imaging polarimeter. The polarizer rotates 360-degree uniform and the signal intensity of the input light is recorded by the imaging polarimeter. The angle of the fast axis of the quarter-waveplate respect to the pass axis of the polarizer can be calculated from the obtained data by use of Fourier series analysis. The mathematic model of the presented method is established and proved by mathematical simulation.
