In order to conduct lunar surface mineral composition studies and content analysis, the Visible and Near-infrared Imaging Spectrometer (VNIS), one of the scientific payloads of the Chang'E 3 Yutu rover, has been developed to detect lunar surface objects and to obtain their reflectance spectra and geometric images. This is achieved with a 45° visual angle and at a height of 0.69 m. VNIS is equipped with a lunar surface calibration function, and the spectral range is 0.45-2.40 μm with a spectral resolution of 2-12 nm. It is capable of synchronously acquiring the full spectrum of lunar surface objects and in situ calibration. Here, we describe the VNIS and explain the preliminary results of the lunar surface exploration and calibration, which provides valuable information for scientific data processing and applications.
为开展月球表面矿物成分研究与含量分析，嫦娥三号玉兔号月球车的科学载荷之一——可见近红外成像光谱仪（VNIS）得以研制，用于探测月球表面物体并获取其反射光谱和几何图像。这是在45°视角和0.69米高度实现的。VNIS具备月球表面校准功能，光谱范围为0.45 - 2.40μm，光谱分辨率为2 - 12nm。它能够同步获取月球表面物体的全光谱并进行原位校准。在此，我们介绍VNIS并阐释月球表面探测与校准的初步结果，这为科学数据处理与应用提供了有价值的信息。
