Abstract: Disclosed herein are systems and devices for use in determining a level of a trait in an agriculture or food product sample. Further disclosed is a portable spectrometer system coupled with chemometric analysis methods to determine a level of a trait in an agriculture or food product sample, the portable spectrometer system comprising: a spectrometer; a sample stage adjacent the spectrometer; a motor coupled to the sample stage; and a system housing enclosing the motor and the spectrometer; wherein rotation of the motor rotates the sample stage, and wherein the motor is controllable in response to spectroscopy requirements.

Abstract: A system and method indicate capability for detecting methane leaks inside buildings. This approach provides the ability to detect methane behind high efficiency coated windows and can extract methane concentration (rather than concentration-path length product CL). Lock-in imaging technologies can facilitate lower laser transmitter power. A field deployable, hand held prototype sensor for use in remote sensing a appropriate standoff distances can support operational testing. Distance infrared imaging of methane is feasible. Fully characterized real time image of a methane cloud offers operational advantages in accuracy and safety as compared to current sensors.

Abstract: An apparatus for light detection includes a light, or photon, detector assembly and a dielectric resonator layer coupled to the detector assembly. The dielectric resonator layer is configured to receive transmission of incident light that is directed into the detector assembly by the dielectric resonator layer. The dielectric resonator layer resonates with a range of wavelengths of the incident light.
