Abstract: The example techniques and mechanisms described herein can enable relatively inexpensive and/or relatively fast classification of aqueous samples of bacteria or viruses. The example techniques and mechanisms described herein can enhance prior generations of miniature spectrophotometers to include Mie scattering effects. The example techniques and mechanisms described herein can provide a relatively small increase in cost over prior approaches while providing improved classification accuracy based on addition of Mie scattering data to absorbance and emissions data.

Abstract: An optical spectral sensing system that provides a full-range mid-IR FTIR based measurement for gases and vapors. The system features a small interferometer module which is integrated with a sample cell and solid-state source, that has an optimized optical path matched to the intended concentration ranges for the gas/vapor measurements. The concentration ranges targeted are from % level for high targeted gas concentrations, as provided by short-pathlength gas cells, to parts-per-million (ppm) and for certain gases high parts-per-billion (ppb) for low trace targeted gas concentrations, provided by long-pathlength gas cells. The optics and opto-mechanical components selected are able to provide a spectral range of 400 cm−1 to 5000 cm−1, with nominal spectral resolutions of 4 cm−1 to 16 cm−1, with the potential to extend the resolution from 2 cm−1 out to 32 cm−1. The electronics are optimized to support both the range and spectral resolution based the use of a “universal” mid-IR detector.
