| 摘 要： | 设计了一个应用于成像光谱仪的望远系统，针对成像光谱仪的特点，由前置望远镜及后置光谱仪组成。前置望远系统的参数以及成像质量对整个成像光谱仪应用显得非常重要。设计了一个谱段范围1～2.5 m、视场为28.10.3、相对口径为1/4、焦距长度为60 mm的望远系统。系统在谱段1～2.5 m宽谱段范围内通过玻璃的匹配校正了色差及二级光谱，畸变控制在0.2%以内，很好地保证了与后续光谱仪的对接，此设计可用于航空领域进行大视场、高分辨率成像。

| Abstract: | In view of the characteristics of the imaging spectrometer, a telescope system applied to the imaging spectrometer was designed, which was composed of a pre-telescope and post spectrometer. Pre-telescope system parameters and imaging quality of the application of the imaging spectrometer is very important. Designed a spectral range of 1-2.5 m, field of view of 28.10.3, a relatively large diameter of 1/4, 60 mm focal length of the telescope system. Systems in a wide spectral 1-2.5 m spectral range by the glass and two matching spectral correction of chromatic aberration, distortion control at 0.2%, to ensure good follow-up spectroscopy with the butt, could be used for aviation the large field, high-resolution imaging. |
