本报告回顾了偏振对光度测量和其他与光度测量特别相关的测量的影响。它不应被视为对两极分化的所有方面都是全面的。光学系统引入光束的偏振度随仪器的复杂性而变化。一般来说，在给定的系统中，它取决于波长。此外，任何偏振对光度特性测定的影响将取决于正在进行的实际测量。因此，尽管偏振会对许多光度测量产生非常显著的影响，但很难用一种通用的方式对其进行量化。该报告讨论了包括光源和探测器在内的完整仪器中各个光学元件的偏振效应。 此外，还提供了有关偏振器主要性能的信息，尤其是与光度测定相关的信息。该出版物共有31页和4个表格。

This report reviews the effects of polarization on photometric and other measurements which are of particular relevance to photometry. It should not be regarded as comprehensive with regard to all aspects of polarization. The degree of polarization introduced by an optical system into a beam of light varies with the complexity of the instrument. In general, it is wavelength dependent in a given system. Furthermore, the effect of any polarization on the determination of photometric properties will depend on the actual measurement being undertaken. Thus, although polarization can have a very significant effect on many photometric measurements, it is difficult to quantify this in a generalized way. The report discusses polarization effects in the individual optical components which comprises a complete instrument, including the source and detector.Additional information is given on the main properties of polarizers, particularly those relevant to photometry.The publication contains 31 pages and 4 tables.
