Abstract: A food integrity probe design comprising two illumination fiber rings, allowing for two different simultaneous measurements wherein the inner illumination ring generates a surface reflectance signal on the central detection fibers and the outer illumination ring allows for an additional interactance measurement, probing deeper into the sample than the surface reflectance alone while partially eliminating specular reflection, which reduces the signal quality, through the addition of a ring-shaped diffusor onto the inner illumination ring is disclosed.

Abstract: A system for detection of low concentration of explosives via Raman spectroscopy is disclosed that is more specifically a Raman detection substrate having a surface-enhancement effect by using roughened glass (or “frosted” glass) with a gold/silver nanosponge alloy sputter-deposited onto it under increased pressure resulting in a nano-porous structure to hold the analyte.
