Journal ArticleDOI

LIBS using dual- and ultra-short laser pulses

TL;DR: A simple near-collinear dual-pulse fiber-optic LIBS probe is shown to be useful for enhanced LIBS measurements and non-gated detection of LIBS is shows to be very effective.
Journal ArticleDOI

The SuperCam Instrument Suite on the Mars 2020 Rover: Science Objectives and Mast-Unit Description

Sylvestre Maurice, +166 more
TL;DR: The goal of this work is to provide an understanding of the technical choices made, the constraints that were imposed, and ultimately the validated performance of the flight model as it leaves Earth, and it will serve as the foundation for Mars operations and future processing of the data.
Journal ArticleDOI

Raman and Near-Infrared Studies of an Epoxy Resin:

Abstract: A quantitative comparison of Raman and Fourier transform near-infrared (FT-NIR) spectroscopic techniques for the analysis of epoxy curing is performed. It is shown that the Raman technique yields a linear calibration curve much like FT-NIR. Band assignments in the Raman spectrum of diglycidyl ether of bisphenol-A (DGEBA) were performed by studying Raman spectra of smaller model compounds.
Journal ArticleDOI

Elimination of Background in Fiber-Optic Raman Measurements

TL;DR: In this paper, a novel fiber-optic configuration with forward-scattering light collection is used to measure Raman spectra using long optical fibers with little background interference, which allows control over the sample volume, and measurements can be made at considerable distances from the face of the optrode.
Journal ArticleDOI

Comparison of some fiber optic configurations for measurement of luminescence and Raman scattering.

TL;DR: An analysis of the background fiber emission for a typical silica-on-silica fiber is presented, and the origin (core or cladding) for several prominent Raman peaks is determined.
