Using a pair of orthogonally linearly polarized beams as the light source, the azimuthally polarization axis finder, CCD cameras as image collector and Matlab software to process images, a polarization direction display system for polarized light was presented, which consisted of a He-Ne laser and an azimuthally polarization axis finder. The angle characteristics of this system were researched. The results show that the measurement accuracy is 0.480°, 0.168°, 0.528°, 0.421°and 0.340°, the measurement precision is 0.208°, 0.576°, 0.660°, 0.603° and 0.466° in the case that the polarizing angle of polarizer is 0°, 90°, 180°, 270° and 360°, respectively. By fitting a straight line to the experimental data, the linear correlation coefficient is 0.999 for this system. The elliptical polarization measurement system is constructed with a quarter-wave plate, analyzer and beam splitter with 50:50 splitting ratio. The measurement experiment of elliptically polarized light is completed, and the ellipticity of the elliptic curve is 0.198.
