Abstract: A system and method are provided for forming body structures including energy filters/shutter components, including energy/light directing/scattering layers that are actively electrically switchable. The filters or 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 paid 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: A concealment component for an optical sensor device includes an optical filter and one or more diffusive optical structures. The one or more diffusive optical structures are configured to distribute light in a diffused pattern on an input surface of the optical filter. The optical filter is configured to pass a first set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are associated with a particular wavelength range, and prevent a second set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are not associated with the particular wavelength range, from passing. Preventing the second set of light beams from passing is to cause the second set of light beams to be directed away from or absorbed by the concealment component in a concealment pattern.

Abstract: A near-field probe (and associated method) compatible with near-infrared electromagnetic radiation and high temperature applications above 300° C. (or 500° C. in some applications) includes an optical waveguide and a photonic thermal emitting structure comprising a near-field thermally emissive material coupled to or part of the optical waveguide. The photonic thermal emitting structure is structured and configured to emit near-field energy responsive to at least one environmental parameter of interest, and the near-field probe is structured and configured to enable extraction of the near-field energy to a far-field by coupling the near-field energy into one or more guided modes of the optical waveguide.

Abstract: A spectroscopic sensor includes a wiring substrate having a main surface, a light detector disposed on the main surface of the wiring substrate, a Fabry-Perot interference filter, a spacer which is provided on the main surface of the wiring substrate and supports the Fabry-Perot interference filter so that the Fabry-Perot interference filter and the light detector are separated from each other, and a stem connected to a ground potential. A second current path which has a smaller electric resistance than that of an arbitrary first current path which extends from the Fabry-Perot interference filter to the light detector via the spacer and the wiring substrate is formed between the Fabry-Perot interference filter and the stem.

Abstract: The present invention introduces a high-power beam profiling system with versatile beam sampling capabilities, designed specifically for measuring multi-kilowatt laser beams. To overcome the limitations of traditional sampling devices that scan the laser beam for measurements, my invention employs a rotating beam sampler. This sampler swiftly traverses the beam for a brief period, capturing a momentary sample which is then reflected to a preferred measuring device such as a camera beam profiler. By capturing a snapshot of the beam, the camera determines the beam size efficiently. The device is inherently cooled by the rotating sampler's movement in the air, coupled with the assistance of external cooling nozzles. It comprises a low-reflectivity mirror, a mechanical arrangement for precise positioning of the mirror, a rotating motor, an additional low-reflectivity mirror, a beam profiling camera, and the necessary micro-controller and algorithm for image processing and calculating the beam profiles.
