| 英文摘要 | It is well known that derotator is commonly used to compensate for image rotation in astronomical telescopes. The classical derotator, consisting of three mirrors, is named K-mirror. The main disadvantage of the K-mirror is that it has high instrumental polarization, causing a larger polarization measurement error in polarimetry. In the paper, we proposed a new design of the derotator based on the Mueller matrix transformation theory of mirrors in polarized light. The new designed derotator contains five mirrors and is called five-mirror derotator. It has a very small instrumental polarization, overcoming the shortcomings of the classical K-mirror. A novel method is applied to compensate for the beam shift induced by the thickness of the reflector. From the result of numerical polarization analysis, it is showed that the five-mirror derotator has a significant advantage for the telescopes with a small field of view, especially in polarimetry at longer wavelengths.
