We report on the design, construction, and testing of a four-mirror reflective polarization rotator, proposed by Smith and Koch [J. Opt. Soc. Am. A 13, 2102 (1996)], that rotates by an angle phi the input linear polarization while preserving the input-output beam collinearity. We correct errors in the previous work that led to an incorrect design for a phi = pi/2 rotator. This type of pure rotator is simple and inexpensive, and it is a direct application of the concept of the nonadiabatic geometric phase to polarization rotation. We also present measurements of the polarization rotation for the case of three metallic mirrors with antiparallel input and output beams, a test of geometric phase in polarization optics not done before.
我们报告了一种四镜反射式偏振旋转器的设计、构建和测试情况。该旋转器由史密斯和科赫[《美国光学学会志A》13, 2102 (1996)]提出，它能将输入的线偏振旋转角度φ，同时保持输入输出光束的共线性。我们纠正了先前工作中的错误，这些错误导致了φ = π/2旋转器的设计错误。这种纯旋转器简单且成本低廉，它是将非绝热几何相位概念直接应用于偏振旋转。我们还给出了三金属镜情况下，输入输出光束反向平行时的偏振旋转测量结果，这是之前未进行过的偏振光学中几何相位的测试。
