摘要: We discuss the development of a miniature nearinfrared point spectrometer, operating in 1.7-4µm region, based on acousto-optic tunable filter (AOTF) technology. This instrument may be used to screen and corroborate analyses samples containing organic biomarkers or mineralogical signatures suggestive extant extinct material collected situ from planetary surfaces. The AOTF spectrometer will paired with laser desorption time-offlight (LDTOF) mass prescreen for evidence volatile refractory organics before subsequent measurement. present laboratory analysis geological known astrobiological importance, without biomarkers.
