摘要：

In order to study the relative orientation accuracy of the instrument polarizers in the polarization CCD camera, a fitted function of the instrument signal, cosinusoidally modulated all along the rotation of the test polarizer, is presented. The results of numerical computation show that the relative orientation of the three polarizers in the same spectral band can be within an accuracy of +/- 10' when a specific instrument output signal function is given for the condition that the random noise signal is in the ranges 0-10 (with S/N approximate to 20).
