    Abstract: Systems and methods are disclosed herein for measuring a fundamental mode vibrational spectrum of materials and substances in the Mid-IR spectral range of 2.5 μm to 14 μm wavelength. In one embodiment, a Mid-infrared FT-IR spectrometer system measures, identifies, or quantifies substances in the spectral range 2.5 μm to 14 μm. The system includes an infrared Micro-Electro-Mechanical System (MEMS) single element emitter light source. The light source is configured in operation to be electrically pulsed and to emit electromagnetic radiation in the wavelength range from 2.5 μm to 14 μm and with integral energy concentrating optic to provide energy for a spectral absorption process. A scanning beam splitter is positioned in an interferometer optical path with fixed angle mirrors and a thermal detector having a sensitivity to determine a maximum optical sensitivity of the system.

    Abstract: Embodiments of this invention relate generally to a method for detection of pathogens, biomarkers, or any compound using data fusion and machine learning. The method includes generating, with a first miniature UV absorption spectrometer of a multi-spectral optical device, a first absorption spectral output based on receiving an absorbance light channel from a sample, generating, with a second miniature UV fluorescence spectrometer of the multi-spectral optical device, a second emission spectral output based on receiving an emission light channel from the sample and performing, with the multi-spectral optical device, data fusion between the first absorption spectral output and the second emission spectral output to generate fused data.

    Abstract: Embodiments of this invention relate generally to detection systems and a method for chemical substance detection using UV fluorescence, specular reflectance, and artificial intelligence. In one example, a handheld detection system comprises single or multiple excitation light sources at discrete wavelengths operating in an ultraviolet portion of an electromagnetic spectrum. The single or multiple excitation light sources are operated intermittently, either all in concert or individually, at a frequency of about 100 Hz to 1000 Hz. Multiple detectors are configured as channels to operate at discrete wavelengths to detect a multiplicity of emissions produced by the excitation energy. A multi-channel electronic or software-implemented detector is synchronized in both phase and frequency with the excitation light sources so that a signal of interest is detected in the multiplicity of emissions.

    Abstract: Systems and methods for measuring a fundamental mode vibrational spectrum of materials and substances in the Mid-IR spectral range of 2.5 μm to 14 μm wavelength. are disclosed herein. In one embodiment, a Mid-infrared absorption spectrometer (MIRAS) system includes an infrared Micro-Electro-Mechanical System (MEMS) single element emitter light source. The light source is electrically pulsed and emits electromagnetic radiation in the wavelength range from 2.5 μm to 14 μm and has an integral energy concentrating optic to provide energy for a spectral absorption process. The system includes a scanning high-efficiency infrared spectral grating with self-calibrating feature, configured so that incident energy having absorption information for the spectral absorption process of a sample is within a predefined threshold of a grating blaze angle. The system also includes a single-element thermal detector to receive output energy having the absorption information from the infrared spectral grating.
