标题： An achromatic polarization retarder realized with slowly varying linear and circular birefringence

摘要： 利用线性和圆双折射现象，我们提出一种装置，可以通过预定量改变光束的一般椭圆偏振，从而实现线偏振光和圆偏振光之间的转换或偏振手性的变化。 基于量子光学中两态绝热跟随的类比，所提出的装置对光的频率不敏感——它作为消色差偏振延迟器。 显示英文摘要

摘要： Using the phenomena of linear and circular birefringence we propose a device that can alter general elliptical polarization of a beam by a predetermined amount, thereby allowing conversion between linearly-polarized light and circularly polarized light or changes to the handedness of the polarization. Based on an analogy with two-state adiabatic following of quantum optics, the proposed device is insensitive to the frequency of the light -- it serves as an achromatic polarization retarder.
