A novel method for real-time polarization measurement is presented. The method is based on a space-variant wave plate that we realized as a computer-generated space-variant subwavelength dielectric grating. The Stokes parameters of the incident beam are determined by Fourier analysis of the space-variant intensity transmitted through the grating and an analyzer. We discuss the design and realization of such wave plates and demonstrate our technique with polarization measurements of both polarized and partially polarized CO(2)-laser radiation at a wavelength of 10.6 mum.
提出了一种用于实时偏振测量的新方法。该方法基于一种空间可变波片，我们将其实现为计算机生成的空间可变亚波长介质光栅。通过对透过光栅和分析仪的空间可变强度进行傅里叶分析来确定入射光束的斯托克斯参数。我们讨论了这种波片的设计与实现，并通过对波长为10.6μm的偏振和部分偏振CO₂激光辐射进行偏振测量来演示我们的技术。
