Visible and Near‐infrared Imaging Spectrometer aboard Chinese Chang'E 3 Spacecraft

Wang, Jianyu / He, Zhiping / Shu, Rong / Xu, Rui / Chen, Kai / Li, Chunlai

To achieve the secondary scientific goals of China's lunar exploration, which is mineral detection in the investigation of the terrain by a rover, the Visible and Near‐infrared Imaging Spectrometer (VNIS) has been selected and built as a payload for the measurements of the lunar surface. The VNIS uses acousto‐optic tunable filters as the dispersive elements and provides a programmable spectral range from 0.45 to 2.4 μm. To meet the scientific objective of mineral detection, VNIS not only can collect images and spectral data from the lunar surface to distinguish the materials, but also can identify geometric features of the observed target. In this chapter, the performance specifications and calibration of the VNIS are introduced, and its applications for lunar and deep space exploration are discussed.
