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: An optical wavelength calibrator is configured to be used on premises with instrumentation such as an optical spectrum analyzer. The on-premises calibrator includes both a fixed wavelength source and a tunable wavelength source, with a variable optical attenuator controlling the power level of a calibration beam provided as an output. A controller within the on-premises calibrator is used to generate the control signals for the various components in response to received external commands, typically via from an external GUI of the user's computer system. The controller is used in combination with the tunable wavelength source to provide a series of output calibration signals at different wavelengths, providing the ability to performance calibration across a desired spectral region and not just a single wavelength. The on-premises calibrator maintains real-time wavelength stability of the instrument to minimize down time when compared off-site extensive re-calibration services.

Abstract: The present disclosure relates to assistive mechanisms and methods that aid an operator of a spectrometer to make spectral measurements of a sample, the measurements having a desired quality. The method enables quality spectral measurements quickly and simply, without a prior understanding of a sample's spectrum or of the details as to how the spectrum is measured. Data quality is improved, and the time required to collect the data is reduced. While a specific example of sample optic focus is disclosed in detail, the optimization of numerous other parameters is possible.

Abstract: An initial system and a constraint condition are established. All freeform surfaces are obtained by surface fitting the feature data points to form a first freeform surface imaging optical system. The first freeform surface imaging optical system is taken as the initial system for multiple iterations to obtain a second freeform surface imaging optical system. The second freeform surface imaging optical system is taken as a first base system. A first surface freedom of the first base system is selected, the values nearby the first surface freedom is selected, and surface positions and tilts of the first base system are changed to obtain a third freeform surface imaging optical system that satisfies the constraint condition. A second base system is selected and the method above is repeated. The freeform surface imaging optical system is obtained until all freedoms for surface positions and tilts have been used.
