为了同时测量光束的所有四个斯托克斯参数，使用分束器和两个沃拉斯顿棱镜将光束分成四个独立的光束。对四分量光束的光通量进行线性检测，得到确定四个斯托克斯参数的四个信号。这种分幅式光偏振计（DOAP）完全由波长相关的424矩阵表征，可以通过校准直接确定。该仪器具有快速响应（仅受光电探测器的限制），因为它没有移动部件或调制。
To measure all four Stokes parameters of a light beam simultaneously, the beam is divided into four separate beams using a beamsplitter and two Wollaston prisms. Linear detection of the light fluxes of the four component beams gives four signals that determine the four Stokes parameters. This division-of-amplitude photopolarimeter (DOAP) is completely characterized by a wavelength-dependent 4 2 4 matrix that can be determined directly by calibration. The instrument has a fast response (that is limited only by the photodetectors) as it has no moving parts or modulation.
