Design of Three-in-one Composite Achromatic Compensator

摘要: 光学补偿器是一种光相位可在一定范围内连续可调的延迟器件，是偏光技术中的一个重要光学元件。对于三元复合式补偿器来说，只需转动其中的一个波片便可实现延迟量在0～2π之间连续可调，而且调节方便，调整量大，精度高。本文在复合式补偿器研究基础上，进一步从理论和实验上证明了该补偿器不仅具有相位补偿性能，而且在一定的光谱范围内满足消色差性能，削弱了延迟量对波长的依赖关系，适合于复色光使用。

Abstract: This article introduces a threeinone composite achromatic compensator.The continuous adjustment of retardation from 0 to 2π can be realized by rotating one of the wave plates.As for the compensator,it is characteristic of convenient adjustment, big adjusting range and high degree of accuracy. The theory and experiment show that the most important feature of this composite compensator is its achromaticity in a certain spectral range. the compensator can be used to polychromatic light because its retardation is independent of wavelength.
