The spectrometer includes a laser source configurable to produce a lased light directable towards a target substance, the laser source having a single wavelength and having sufficient power to cause a portion of the target to emit Raman scattering and sufficient to ablate a portion of the target substance to produce a plasma plume. A separate remote light collector is optically configurable to collect light emitted from the portion of the target emitting Raman scattering and from the portion of the target producing the plasma plume. A filter is optically coupled to the remote light collector to remove reflected light and Rayleigh-scattered light, and a spectroscope is optically coupled to the filter and configured to separate the collected and filtered light into a frequency spectrum comprising a Raman spectrum and a laser-induced breakdown spectrum. Finally, an electronic light sensor is used to record the frequency spectrum.

Abstract: Method/system locate external articles using source, detector (PSD), entrance aperture, and magnifying/reducing afocal element—expanding FOR>90°, or refining precision. Between (1) source or detector and (2) aperture, at least one plural-axis-rotatable mirror addresses source/detector throughout FOR. ½- to 15-centimeter mirror enables ˜25 to ˜45 μradian beam divergence. Aperture, afocal element, and mirror(s) define source-detector path. Mirror(s) rotate in refractory- (or air/magnetic-) bearing mount; or mirror array. Auxiliary optics illuminate mirror back, monitoring return to measure (null-balance feedback) angle. To optimize imaging, auxiliary radiation propagates via splitters toward array (paralleling measurement paths), then focusing on imaging detector. Focal quality is developed as a PSF, optimized vs. angle; stored results later recover optima. Mirror drive uses magnet(s) on mirror(s). “Piston” motion yields in-phase wavefronts, so array dimensions set diffraction limit. Also: destructive reply; scaling optimizes acceleration vs. thickness; passive systems.
