Abstract: Innovative techniques that result in a better signal-to-noise ratio for spectrographic analysis of substances in a target than conventional techniques. In these techniques, light illuminates a target with at least some of the light penetrating the target. At least a portion of the light that penetrates the target is collected from a region on the target's surface that is not directly illuminated. Preferably, at least a majority of the collected light is light that penetrates the target. Also preferably, the light that illuminates the target is in a pattern that partially but not completely surrounds the region from which the portion of the light that penetrates the target is collected. A spectrum of at least a portion of the collected light is analyzed.
