    Abstract: An imaging system includes a plurality of optical sensors arranged on an integrated circuit in an array with a plurality of rows and a plurality of columns. The system includes an interface communicating with the plurality of optical sensors, memory storing operational instructions and processing circuitry configured to sample an image using the plurality of optical sensors in a first mode and sample at least a portion of the image sequentially on a row-by-row basis at a predetermined sampling rate in a second mode to produce row by row sample outputs. The processing circuitry is further configured to initiate sampling at least some rows of the plurality of rows of optical sensors using different time stamps.

    Abstract: A filter array according to one aspect of the present disclosure is provided with filters arranged two-dimensionally. The filters include multiple types of first filters having mutually different transmission spectra, of which each transmission spectrum includes first peaks, and multiple types of second filters having mutually different transmission spectra, of which each transmission spectrum includes one or more second peaks. The number of the first peaks in the transmission spectrum of each of the multiple types of first filters is greater than the number of the one or more second peaks in the transmission spectrum of each of the multiple types of second filters, and the multiple types of first filters and the multiple types of second filters are disposed in a mixed arrangement.

    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: Aspects relate to mechanisms for increasing the field of view of a spectrometer. An optical device may be configured to simultaneously couple light from different locations (spots) on a sample to the spectrometer to effectively increase the spectrometer field of view. The optical device can include a beam combiner and at least one reflector to reflect light beams from respective spots on the sample towards the beam combiner. The beam combiner can combine the received light beams from the different spots to produce a combined light beam that may be input to the spectrometer.

    Abstract: A CubeSat compatible spectrometer including a slit having a first length and first width; a diffraction grating; and a two dimensional focal plane array electromagnetically coupled to the diffraction grating. The 2D focal plane array includes an array of pixels including a plurality of sets of pixels. Diffraction of electromagnetic radiation transmitted through the slit by the diffraction grating forms a plurality of beams, each of the beams comprising a different one of the bands of the wavelengths in the electromagnetic radiation, and each of the beams transmitted onto a different one of the sets of the pixels.

    Abstract: A spectroreflectometric system for performing a spectral analysis on the fundus of a patient's eye or other medium is provided. The system includes an imaging device and a spectral analyser. Illumination light from an illumination light source is projected towards the fundus of the patient's eye. The resulting light from the fundus is separated by a beam splitter into an imaging portion travelling along an imaging light path to reach the imaging device and a spectral analysis portion deviated to a spectral analysis light path. The system further includes a pointer light source optically coupled to the spectral analysis light path. The system is operable in an acquisition mode to concurrently obtain an image of the fundus of the patient's eye and a spectral analysis of an analysis spot on this fundus, and in a pointer mode to obtain a visual representation of the analysis spot within the image.
