High-brightness synchrotron radiation sources provide highly polarized x-rays for a broad range of studies in materials science, biology, chemistry, and physics. Special insertion devices and x-ray optics such as phase plates can further enhance the purity and the tunability of the polarization of a synchrotron x-ray beam. There are therefore growing interests and activities in making better polarized x-ray sources, and analyzing complete polarization states (Stokes polarimetry) of an x-ray beam. In this paper we review the present status of x-ray optics development in this field. We will focus on the principles and the practicalities of the various methods for producing and analyzing polarized x- rays, especially circularly polarized x-rays.
