【摘要】：采用光路展開法,利用調(diào)制度與相位誤差兩種判據(jù),分析平行轉(zhuǎn)鏡在轉(zhuǎn)動過程中的晃動、平行轉(zhuǎn)鏡的平行度、定鏡的傾斜誤差以及視場角等因素對平行轉(zhuǎn)鏡式光譜儀誤差容限的影響.分析表明:平行轉(zhuǎn)鏡的晃動是平行轉(zhuǎn)鏡式光譜儀最重要的影響因素,但由于平行轉(zhuǎn)鏡的連續(xù)快速轉(zhuǎn)動,慣性的作用會顯著降低轉(zhuǎn)動過程中的晃動影響;系統(tǒng)對平行轉(zhuǎn)鏡的平行度不敏感,對定鏡的傾斜與視場角的誤差容限與傳統(tǒng)邁克爾遜式光譜儀相同.相對于傳統(tǒng)直線往復(fù)運動式的光譜儀,平行轉(zhuǎn)鏡式光譜儀具有更高的探測速度與穩(wěn)定性.同時,誤差容限分析也為該光譜儀的系統(tǒng)設(shè)計與裝調(diào)提供了理論指導(dǎo).
[Abstract]:By using the optical path expansion method and the two criteria of modulation and phase error, the sloshing of the parallel rotating mirror and the parallelism of the parallel rotating mirror are analyzed. The influence of tilt error and field of view angle on the error tolerance of parallel rotating mirror spectrometer. The analysis shows that the sloshing of the parallel rotating mirror is the most important factor in the parallel rotating mirror spectrometer, but due to the continuous and rapid rotation of the parallel rotating mirror, the effect of inertia will significantly reduce the sloshing effect in the process of rotation. The system is not sensitive to the parallelism of the parallel rotating mirror, and the error tolerance of the tilt and the field of view angle of the fixed mirror is the same as that of the traditional Michelson spectrometer. Compared with the traditional linear reciprocating spectrometer, the parallel rotating mirror spectrometer has higher detection speed and stability. At the same time, the error tolerance analysis also provides theoretical guidance for the system design and installation of the spectrometer.
