摘要： The disclosure relates to a substrate material for the improved detection, resolution and imaging of biological material for spectroscopic characterization by Raman of optical imaging spectroscopy. The substrate provides a uniform, optically flat, highly reflective surface which can be made hydrophobic to prevent spreading of the sample and facilitating its optical evaluation. Moreover, the substrate can be coated with a material that does not emit Raman scattered photons when exposed to said illuminating photons. The principles disclosed herein allow a low spectroscopic background particularly suitable for examining small samples or samples having low concentrations of the suspected component.

摘要： A compact imaging spectrometer comprises an entrance slit, a catadioptric lens with a mirrored surface, a grating, and a detector array. The entrance slit directs light to the mirrored surface of the catadioptric lens; the mirrored surface reflects the light back through the lens to the grating. The grating receives the light from the catadioptric lens and diffracts the light to the lens away from the mirrored surface. The lens transmits the light and focuses it onto the detector array.

摘要： A method for determining a calibration function includes: calculating a first distance, between a distribution of target spectra and a comparison distribution of spectra; calibrating the distribution of target spectra with a first preliminary calibration function to form a first distribution of calibrated target spectra; calculating a second distance, between the first distribution of calibrated target spectra and the comparison distribution of spectra; determining that the second distance is less than the first distance; and setting the calibration function equal to the first preliminary calibration function.

摘要： 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.

摘要： A method and device (10) for making a calibrated measurement of light from an object (E). In a first measurement window (W1), object light (LE) is received from the object (E) onto a beam splitter (11) which splits the light into a signal path (Ps) and a reference path (Pr). A first signal (S1=T·LE·Hs) is measured by a signal detection element (15s) in the signal path (Ps). A second signal (S2=R·LE·Hr) is measured by a reference detection element (15r) in the reference path (Pr). In a second measurement window (W2), calibration light (LC) is received onto the beam splitter (11). A third signal (S3=R·LC·Hs) is measured by the signal detection element (15s) in the signal path (Ps). A fourth signal (S4=T·LC·Hr) is measured by the reference detection element (15r) in the reference path (Pr). A measurement value of the object light (LE) is determined based on the measured signals (S1,S2,S3,S4).

摘要： Aspects of the present disclosure provide a method for wavelength calibration of a spectrometer. The method can include receiving a calibration light signal having first spectral components of different first wavelengths; separating and projecting the first spectral components onto pixels of a detector of the spectrometer; establishing a relation between the first wavelengths and pixel numbers of first pixels on which the first spectral components are projected; calculating first residual errors between the first wavelengths and estimated wavelengths that are associated by the relation to the pixel numbers of the first pixels; receiving an optical signal having a second spectral component of a second wavelength; projecting the optical signal onto a second pixel; and calibrating the second wavelength based on a second residual error calculated based on one of the first residual errors that corresponds to a pair of the first pixels between which the second pixel is located.
