ISO 12005:2003规定了一种确定偏振状态的方法，以及尽可能确定连续波（cw）激光束偏振度的方法。它也可以应用于重复脉冲激光器，前提是它们的电场矢量方向不随脉冲而改变。ISO 12005:2003还规定了在线偏振（全部或部分）激光束的情况下确定振荡平面方向的方法。假设激光辐射是准单色的，并且对于测量而言足够稳定。对于具有高发散角的激光器的某些应用，偏振状态的知识可能非常重要，例如，当此类激光器的光束应与偏振相关设备（例如偏振保持光纤）耦合时。ISO 12005:2003还规定了测定高度发散激光束偏振状态的方法，以及测量大孔径光束的方法。

ISO 12005:2003 specifies a method for determining the polarization status and, whenever possible, the degree of polarization of the beam from a continuous wave (cw) laser. It can also be applied to repetitively pulsed lasers, if their electric field vector orientation does not change from pulse to pulse.ISO 12005:2003 also specifies the method for determining the direction of the plane of oscillation in the case of linearly polarized (totally or partially) laser beams. It is assumed that the laser radiation is quasi-monochromatic and sufficiently stable for the purpose of the measurement.The knowledge of the polarization status can be very important for some applications of lasers with a high divergence angle, for instance when the beam of such a laser shall be coupled with polarization dependent devices (e.g. polarization maintaining fibres). ISO 12005:2003 also specifies a method for the determination of the state of polarization of highly divergent laser beams, as well as for the measurement of beams with large apertures.
