Portable Raman spectroscopy systems enable remote mineral identification for planetary exploration. These compact devices offer stand-off measurements up to 15 meters, crucial for field analysis.

Area of Science:

  • Planetary Science
  • Spectroscopy
  • Analytical Chemistry

Background:

  • Remote sensing is vital for planetary exploration.
  • Stand-off Raman spectroscopy offers non-invasive chemical analysis.
  • Developing transportable systems is key for field deployment.

Purpose of the Study:

  • To evaluate compact, transportable Raman systems for stand-off measurements (<20 m).
  • To assess the performance of acousto-optic tunable filters (AOTF) for spectral selection.
  • To optimize remote Raman spectral acquisition under various conditions.

Main Methods:

  • Four variations of stand-off Raman systems with telescope-based light collection were developed.
  • Fiber-optic and lens-coupling to detection systems were investigated.
