The invention discloses a
system and method for analysis of Martian mineral components by using double
multiplexing laser spectrum. The
system includes an optical head, a short
wavelength spectrometer, a
medium wave spectrometer, a
long wavelength spectrometer, a calibration board bracket, a calibration board, a pointing mirror bracket, a two-dimensional pointing mirror, a two-dimensional
rotation control component, a pointing mirror control cable and a load controller. Based on the
system, the combined detection of atom and molecular can be achieved by combined detection of
laser induced
plasma spectroscopy and
laser Raman spectroscopy. The invention provides a double
multiplexing laser spectrum detection system and method; a same pulse
laser source and three frequency multiplication modules are used to realize the
multiplexing of light sources; and short, middle and long wave spectrometers in the same length and the corresponding spectrum ICCD area array detectors are used to achieve the multiplexing of beam split and spectral detection. In addition, remote micro area imaging and laser self-focusing function are achieved to share a main
optical path. The invention effectively expands the scope of Martian
mineral analysis, and the system is compact and convenient, reduces the
fluorescence interference and improves the comprehensiveness of molecular detection.
