Raman spectroscopy is a well-established method for chemical identification, with wide variety of applications. The two major limitations are that fluorescence can hamper detection, and imaging slow; it typically takes multiple hours to measure even small surface area. We have developed multimodal setup mitigates these limitations. has point-scanning mode allows time-gated as well continuous spectroscopy, both modes use an 80 MHz, 532 nm excitation laser up 20 W power. suppression...
Abstract One of the primary goals in space research is search for signs extant or extinct extraterrestrial life, and Raman spectroscopy can play a role this field. spectrometers are planned future missions to Mars possibly Moon identify mineralogical surface composition potentially existing organic compounds (especially on Mars). However, major challenge spectroscopy, especially visible range, strong fluorescence background. Time‐resolved (TRRS) provide selective detection signals over...
Abstract Mars is one of the prime candidates in search for extraterrestrial life. At most comparable terrestrial Martian analogue sites, life often occurs endolithic form; i.e. hiding below surface. To detect biomarkers life, two promising options are drilling or measuring through surface, latter being less invasive and preferable. Raman spectroscopy an established chemical identification method, advanced modes have been developed sub-surface analysis. Time-resolved (TRRS), based on...
