Abstract: A photodetector array comprising at least one first sensor and at least one second sensor on the horizontal surface of the array substrate. The at least one first sensor is sensitive to radiation in a first wavelength range which comprises long-wavelength infrared wavelengths, and the at least one second sensor is sensitive to radiation in a second wavelength range which comprises wavelengths shorter than long-wavelength infrared. The array substrate comprises a vertical cavity on its horizontal surface, and the first sensor comprises a layer of pyroelectric material (65) which extends horizontally across the vertical cavity in the first area. A first part of a layer of two-dimensional layered material at least partly covers the layer of pyroelectric material (65), and a second part of the layer of two-dimensional layered material at least partly covers the foundation of the second sensor.

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: A light detecting device includes: a filter array including filters two-dimensionally arrayed and an image sensor including light detection elements. Each of first and second filters included in the filters includes a first reflective layer, a second reflective layer, and an intermediate layer therebetween and has a resonance structure having resonant modes whose orders are different from each other. A refractive index and/or a thickness of the intermediate layer in the first and second filters is different depending on the filter. A transmission spectrum of each of the first and second filters has local maximum value of transmittance at each of wavelengths included in a wavelength region, and the wavelengths correspond to the resonant modes, respectively. The image sensor is disposed at a position where the image senor receives passing light that passes through the filter array, to detect components in the wavelengths included in the passing light.

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: Various embodiments disclosed herein describe a divided-aperture infrared spectral imaging (DAISI) system that is adapted to acquire multiple IR images of a scene with a single-shot (also referred to as a snapshot). The plurality of acquired images having different wavelength compositions that are obtained generally simultaneously. The system includes at least two optical channels that are spatially and spectrally different from one another. Each of the at least two optical channels are configured to transfer IR radiation incident on the optical system towards an optical FPA unit comprising at least two detector arrays disposed in the focal plane of two corresponding focusing lenses. The system further comprises at least one temperature reference source or surface that is used to dynamically calibrate the two detector arrays and compensate for a temperature difference between the two detector arrays.
