Abstract: A problem addressed by the present invention is to reduce the influence of stray light incident on each light-receiving element in the case of receiving each wavelength of light using a plurality of light-receiving elements. The multichannel spectrophotometer according to the present invention is a detector for simultaneously detecting the entirety of wavelength-dispersed light obtained by introducing light from a sample to a light-dispersing element (16) and dispersing this light into wavelengths by the light-dispersing element (16), including: a multichannel-type detector (17) including a plurality of light-receiving elements arranged in a one-dimensional form in a wavelength-dispersing direction of the light-dispersing element; a light amount calculator (221) for calculating the amount of light from a detection signal of each of the plurality of light-receiving elements (PD); a spectrum creator (222) for creating, from the amounts of light calculated by the light amount calculator (221), a spectrum showing a relationship between wavelength and the amount of light; and a computing section (224) for estimating, from the spectrum, the amount of stray light incident on each light-receiving element (PD) and correcting the spectrum by subtracting, from the amount of wavelength-dispersed light incident on each light-receiving element, the amount of stray light.

Abstract: A spectrometer includes a support having a bottom wall part in which a depression is provided and a side wall part, a light detection element supported by the side wall part while opposing the depression, a resin layer disposed at least on an inner surface of the depression, and a dispersive part provided in the resin layer on the inner surface of the depression. The resin layer is in contact with an inner surface of the side wall part. A thickness of the resin layer in a first direction in which the depression and the light detection element oppose each other is larger in a part in contact with the inner surface of the side wall part than in a part disposed on the inner surface of the depression.

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: MIR spectroscopy systems comprising hierarchical spectral dispersion that enables fine spectral resolution and high sensitivity spectroscopy are disclosed. Hierarchical spectral dispersion is derived by employing at least two diffractive lens arrays, located on either side of a test sample, each receiving input radiation having an input spectral range and distributing the input radiation into a plurality of output signals, each having a fraction of the spectral range of the input radiation. As a result, the signal multiplication factor of the two arrays is multiplied in a manner that mitigates the propagation of wavelength harmonics through the system. In some embodiments, an emitter array comprising a plurality of spectrally selective emitters provides the input MIR radiation to a spectroscopy system. In some embodiments, spectrally selective detectors are used to detect narrow spectral components in the radiation after they have passed through the test sample.

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.

Abstract: In a hyperspectral imaging system and method, a pixilated imaging sensor array receives light reflected from, transmitted through, or scattered by a target scene. Images of the target scene are acquired at a number of times and these images are processed to generate hyperspectral data for each pixel of the imaging sensor array based on data for the pixel included in each of the acquired images. This processing can include spatially aligning two or more of the images that were spatially shifted with respect to each other when acquired based on at least one common image feature in the images.

Abstract: A spectral imaging device is configured to capture color images synchronized with controlled illumination from different color light emitting diodes. A processor in the device applies a coupling factor to sampled color images to convert sampled pixels into spectral channels corresponding to LED color and color filter. Multi-spectral spectricity vectors produced at pixel locations are used along with spatial information to classify objects, such as produce items.
