Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.

Abstract: A system and method are provided for forming energy filter layers or shutter components, including energy/light directing/scattering layers that are actively electrically switchable. The energy filters or shutter components are operable between at least a first mode in which the layers, and thus the presentation of the shutter components, appear substantially transparent when viewed from an energy/light incident side, and a second mode in which the layers, and thus the presentation of the energy filters or shutter components, appear opaque to the incident energy impinging on the energy incident side. The differing modes are selectable by electrically energizing, differentially energizing and/or de-energizing electric fields in a vicinity of the energy scattering layers, including electric fields generated between a pair of transparent electrodes sandwiching an energy scattering layer. Refractive indices of transparent particles, and the transparent matrices in which the particles are fixed, are tunable according to the applied electric fields.

Abstract: Systems, tools, and methods are disclosed that utilize at least one integrated computational element to measure a property of a substance in close proximity to the substance's source. More specifically, systems, tools, and methods are presented that allow the interaction of electromagnetic radiation and the optically-processing of interacted electromagnetic radiation in proximity to an emergence of a fluid from the fluid's source. The integrated computational elements optically-process the interacted electromagnetic radiation into a weighted optical spectrum. The weighted optical spectrum enables the determination of various chemical or physical characteristics of the fluid.
