Abstract: A device for multispectral imaging in the infrared, suitable for detecting at at least one first and one second detection wavelength is provided. It comprises a detection matrix array comprising a set of elementary detectors of preset dimensions forming an image field of given dimensions; and an image-forming optic having a given aperture number (N) and a given focal length (F), which aperture number and focal length are suitable for forming, at any point of the image field, an elementary focal spot covering a set of at least two juxtaposed elementary detectors. The device furthermore comprises a matrix array of elementary metal-dielectric guided-resonance filters, which matrix array is arranged in front of the detection matrix array at a distance smaller than a focal depth of the optic, the dimensions of the elementary filters being such that each elementary focal spot formed at each point of the image field covers at least two elementary filters; and the elementary filters are optimised for pass-band transmission in spectral bands centred on two different central wavelengths, equal to two of said detection wavelengths.

Abstract: Multispectral images, including ultraviolet light and its interactions with ultraviolet light-interactive compounds, can be captured, processed, and represented to a user. Ultraviolet-light related information can be conveniently provided to a user to allow the user to have awareness of UV characteristics and the user's risk to UV exposure.

Abstract: Provided are a dual coupler device configured to receive lights of different polarization components, a spectrometer including the dual coupler device, and a non-invasive biometric sensor including the spectrometer. The dual coupler device may include, for example, a first coupler layer configured to receive a light of a first polarization component among incident lights. and a second coupler layer configured to receive a light of a second polarization component among the incident lights, wherein a polarization direction of the light of the first polarization component is perpendicular to a polarization direction of the light of the second polarization component. The first coupler layer and the second coupler layer may be spaced apart from each other and extended along a direction in which the light propagates in the first coupler layer and the second coupler layer.

Abstract: The present disclosure generally relates to hyperspectral spectroscopy, and in particular, to systems, methods and devices enabling a single-sensor hyperspectral imaging device. Hyperspectral (also known as “multispectral”) spectroscopy is an imaging technique that integrates multiples images of an object resolved at different narrow spectral bands (i.e., narrow ranges of wavelengths) into a single data structure, referred to as a three-dimensional hyperspectral data cube. Data provided by hyperspectral spectroscopy allow for the identification of individual components of a complex composition through the recognition of spectral signatures of individual components within the three-dimensional hyperspectral data cube.

Abstract: Systems in a flow cytometer having an interrogation zone and illumination impinging the interrogation zone include: a lens subsystem including a collimating element that collimates light from the interrogation zone, a light dispersion element that disperses collimated light into a light spectrum, and a focusing lens that focuses the light spectrum onto an array of adjacent detection points; a detector array, including semiconductor detector devices, that collectively detects a full spectral range of input light signals, in which each detector device detects a subset spectral range of the full spectral range of light signals; and a user interface that enables a user to create a set of virtual detector channels by grouping detectors in the detector array, such that each virtual detector channel corresponds to a detector group and has a virtual detector channel range including the sum of subset spectral ranges of the detectors in the corresponding detector group.

Abstract: A compact spectrometer includes an excitation light source configured to generate excitation light and arranged to illuminate a spot on a sample. A dispersive element includes at least one movable component and spatially separates output light emanating from the sample in response to the excitation light into a plurality of different wavelength bands. A moveable component of the dispersive element causes the plurality of different wavelength bands of the output light to be scanned across a detector. The detector includes at least one light sensor that senses the wavelength bands of the output light and generates an output electrical signal in response to the sensed output light.

Abstract: The multispectral detection device comprises first and second photodetectors sensitive to two different wavelengths. The two photodetectors are connected to two integration capacitors of two different readout circuits. Two reset circuits are configured so as to initialise the two integration capacitors separately. A first synchronisation circuit is connected to the first readout circuit and to the synchronisation signal and clock signal generators. The first synchronisation circuit is configured in such a way as to define the frame by detection of a leading edge of the synchronisation signal, count the number of occurrences of a trailing edge of the clock signal, initiate or terminate a data acquisition phase when the number of occurrences of trailing edges is equal to a threshold value recorded in a register of the first synchronisation circuit.

Abstract: A wideband spectrograph apparatus includes a first spectrograph assembly and one or more subsequent spectrograph assemblies. Each subsequent spectrograph assembly is optically coupled to a previous spectrograph assembly and is configured to receive a cascading beam from one or more dispersion elements of the previous spectrograph assembly. The first spectrograph assembly is configured for detecting illumination in a first wavelength range and the one or more subsequent spectrograph assemblies are configured for detecting illumination in wavelength ranges different from the first or any previous wavelength ranges to provide simultaneous sampling of different spectral portions of an input beam.
