Abstract: A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.

Abstract: A calibration target for a hyperspectral image sensor can include a panel with a predetermined length and width. The calibration target can also include a dispersive fabric overlaying a surface of the panel that refracts and disperses light illuminated from an illumination source to provide light on a plurality of different spectral bands corresponding to spectral bands detectable by the hyperspectral image sensor.

Abstract: A system of measuring hemoglobin and bilirubin parameters in a whole blood sample using optical absorbance. The system includes an optical-sample module, a spectrometer module, an optical fiber module optically connecting the optical-sample module to the spectrometer module, and a processor module. The optical-sample module has a light-emitting module having a LED light source, a cuvette and a calibrating-light module. The processor module receives and processes an electrical signal from the spectrometer module and transforms the electrical signal into an output signal useable for displaying and reporting hemoglobin parameter values and/or total bilirubin parameter values for the whole blood sample.

Abstract: A system and method of optical spectrum analysis that circumvents the trade-off between resolution and sensitivity by combining two spectral measurements: a first spectrum (102) from first spectral measurement means (240), having high resolution and low sensitivity; and a second spectrum (103) from second spectral measurement means (220), having lower resolution but higher resolution. The input of the of the first spectral measurement means (240) is amplified by an optical amplifier (230), being the effects induced by said amplifier (230) on the first spectrum (102) corrected at processing means (270) by comparison with the second spectrum (103).

Abstract: A method for deriving a background-corrected portion of a measured optical emission spectrum comprising the steps of identifying two or more background correction points from the portion of the measured emission spectrum; deriving a background correction function fitted to the identified background correction points, and applying the background correction function to the portion of the measured emission spectrum so as to produce a background-corrected portion of the emission spectrum, wherein the background correction points are identified from the measured data points by consideration of the gradients between the measured data points.

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.
