由WMAP证实的DASI对CMB极化的发现开启了宇宙学的新篇章。大多数关于暴胀引力波和再电离的有用信息都是在大角度尺度上的，银河前景污染是最严重的。本综述的目标是从实用的角度提供最先进的微波背景极化，将真实世界的数据与物理模型联系起来。我们提出了这种极化现象的物理性质，并说明了它如何依赖于标准绝热模型的各种宇宙学参数。我们还提出了迄今为止所有的观测限制，并讨论了迄今为止我们从CMB研究中了解到的偏振前景。最后，对微波背景偏振测量的发展前景进行了展望。
The DASI discovery of CMB polarization, confirmed by WMAP, has opened a new chapter in cosmology. Most of the useful information about inflationary gravitational waves and reionization is on large angular scales where Galactic foreground contamination is the worst. The goal of the present review is to provide the state-of-the-art of the CMB polarization from a practical point of view, connecting real-world data to physical models. We present the physics of this polarized phenomena and illustrate how it depends of various cosmological parameters for standard adiabatic models. We also present all observational constraints to date and discuss how much we have learned about polarized foregrounds so far from the CMB studies. Finally, we comment on future prospects for the measurement of CMB polarization.
