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.
利用线性和圆双折射现象，我们提出了一种可以按预定量改变光束一般椭圆偏振的装置，从而可以在线偏振光和圆偏振光之间进行转换，或者改变偏振的手性。基于与量子光学的两态绝热跟踪的类比，所提出的装置对光的频率不敏感——它是一种消色差偏振延迟器。
