An In-situ Fine Spectral Analysis System for Planetary Surfaces

Abstract

The invention discloses an in-place fine spectral analysis system for the planetary surface. The system comprises a calibration dustproof module, a spectral analysis module, a data acquisition and control module, and a mounting base. The instrument employs a multi-radio-frequency composite acousto-optic drive technology and adopts dual-channel discrete detection to realize target image and spectral data acquisition for fine spectral analysis. A light rotating mechanism is adopted to drive an integrated calibration dustproof plate, and a pointing mirror is adopted in a matching mode so as to achieve the functions of planetary surface detection, calibration, dust prevention and heat preservation in harsh environments. A complex optical mechanism design is adopted to make the instrument compact, light and small. The instrument of the invention has the characteristics of high degree of integration, smallness, lightness and multiple functions, has the function of non-programmed self fine spectral analysis, can adapt to harsh planetary surface environments, and meets the requirements of deep-space planetary surface detection for novel instruments.
