摘要：A method and apparatus for automated spectral calibration of a spectroscopydevice. In one embodiment, the disclosure relates to a method for simultaneouscalibration and spectral imaging of a sample by: simultaneously illuminating the sample

and a calibrant with a plurality of illuminating photons; receiving, at the spectrometer, afirst plurality of photons collected from the sample and a second plurality of photonscollected from the calibrant; forming a calibrant spectrum from the first plurality ofcollected photons and a sample spectrum from the second plurality of collectedphotons; comparing the calibrant spectrum with a reference spectrum of the calibrant todetermine a wavelength-shift in the calibrant spectrum; applying the wavelength-shift tothe sample spectrum to obtain a calibrated sample spectrum; and forming a spatiallyaccurate wavelength resolved image of the sample from the first plurality of collectedphotons.
