Abstract: Devices and methods of the present technology utilize wavelength-dependent transmittance of 2D materials to identify the wavelength of an electromagnetic radiation. A wide range of 2D materials can be used, making possible the use of the technology over a large portion of the electromagnetic spectrum, from gamma rays to the far infrared. When combined with appropriate algorithms and artificial intelligence, the technology can identify the wavelength of one or more monochromatic sources, or can identify color through the use of a training set. When applied in an array format, the technology can provide color imaging or spectral imaging using different regions of the electromagnetic spectrum.

Abstract: The present invention provides a wide-filed spectral imaging system including a laser generator, a wavelength adjustment module, an objective lens, and a single-pixel imaging and a spectral separating module. The laser generator is configured to generate a laser excitation beam. The wavelength adjustment module is configured to disperse the laser excitation beam into a plurality of beams of different wavelengths. The objective lens is configured to focus the plurality of beams of different wavelengths on a sample to excite molecules under test in the sample and generate an emission light. The single-pixel imaging and spectral separating module is configured to generate a series of patterns and modulate the emission light with the series of patterns to generate a diffracted beam. The single-pixel imaging and spectral separating module further disperses the wavelength of the diffracted beam, collects light signals of the expanded diffracted beam, and performs a spectral image reconstruction.

Abstract: A system and method are provided for forming electromagnetic energy transmissive layers, which are particularly configured to selectively scatter specific and selectable wavelengths of electromagnetic energy, while allowing remaining wavelengths to pass therethrough. Processes are provided by which to form, or otherwise incorporate, one or more energy scattering layers, including uniquely implementing optical light scattering techniques in such energy scattering layers, and to objects, object portions, wall plates, lenses, filters, screens and the like that are formed of, or that otherwise incorporate, such transmissive energy-scattering layers. Refractive indices of particles fixed in a matrix are tunable in order that the finished layers provide an opaque appearance when viewed from an energy-incident excited by light in the visible spectrum. A color, pattern, texture or image of the scattering layer may be rendered according to an individual user's desires, the layers being substantially-transparent to light passing through layers.

Abstract: In one embodiment, a flow cytometer is disclosed having a compact light detection module. The compact light detection module includes an image array with a transparent block, a plurality of micro-mirrors in a row coupled to a first side of the transparent block, and a plurality of filters in a row coupled to a second side of the transparent block opposite the first side. Each of the plurality of filters reflects light to one of the plurality of micro-mirrors and passes light of a differing wavelength range and each of the plurality of micro-mirrors reflects light to one of the plurality of filters, such that incident light into the image array zigzags back and forth between consecutive filters of the plurality of filters and consecutive micro-mirrors of the plurality of micro-mirrors. A radius of curvature of each of the plurality of micro-mirrors images the fiber aperture onto the odd filters and collimates the light beam on the even filters.

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: An approach to noninvasively and remotely detect the presence, location, and/or quantity of a target substance in a scene via a spectral imaging system comprising a spectral filter array and image capture array. For a chosen target substance, a spectral filter array is provided that is sensitive to selected wavelengths characterizing the electromagnetic spectrum of the target substance. Elements of the image capture array are optically aligned with elements of the spectral filter array to simultaneously capture spectrally filtered images. These filtered images identify the spectrum of the target substance. Program instructions analyze the acquired images to compute information about the target substance throughout the scene. A color-coded output image may be displayed on a smartphone or computing device to indicate spatial and quantitative information about the detected target substance. The system desirably includes a library of interchangeable spectral filter arrays, each sensitive to one or more target substances.
