光谱偏振测量和控制具有许多独特的特点，适用于各种光谱仪器。它利用了高阶延迟器偏振延迟时的强色散特性，从而可以在不使用机械或有源元件进行偏振调制的情况下实现偏振调制。在这篇报告中，我们描述了它的原理，基本特征，和几个应用，包括光谱椭偏仪和光束轮廓和偏振的超快旋转。
Spectroscopic polarization measurement and control using channeled spectrum has several unique features and is useful for various spectroscopic instruments. It utilizes the strong dispersion characteristics in polarization retardation of high-order retarders so that the polarization modulation can be made without using mechanical or active elements for polarization modulation. In this presentation, we describe its principle, basic features, and several applications including a spectroscopic ellipsometer and ultrafast rotations of beam profile and polarization.
