    Abstract: The disclosure features methods that include obtaining multispectral image information for a sample that includes a fluorescent dye, calculating from an image cube of the information a first spectrum and a second spectrum, and calculating a pure spectrum of the fluorescent dye in the sample based on the first and second spectra, where a relative contribution of light emission from the fluorescent dye to the second spectrum is larger than a relative contribution of light emission from the fluorescent dye to the first spectrum, where calculating the first and second spectra includes identifying corresponding first and second sets of pixel intensity values in the image cube, and where identifying the first set of pixel intensity values includes designating one or more layers of the image cube as a first layer set.

    Abstract: A method for determining spectral calibration data (λcal(Sd), Sd,cal(λ)) of a Fabry-Perot interferometer (100) comprises: - forming a plurality of filtered spectral peaks (P'1, P'2) by filtering input light (LB1) with a Fabry-Perot etalon (50) such that a first filtered peak (Ρ'1) corresponds to a first transmittance peak (P1) of the etalon (50), and such that a second filtered peak (P'2) corresponds to a second transmittance peak (P2) of the etalon (50), - using the Fabry-Perot interferometer (100) for measuring a spectral intensity distribution (M(Sd)) of the filtered spectral peaks (Ρ'1, P'2), wherein the spectral intensity distribution (M(Sd)) is measured by varying the mirror gap (dFP) of the Fabry-Perot interferometer (100), and by providing a control signal (Sd) indicative of the mirror gap (dFP), and - determining the spectral calibration data (λcal(Sd), Sd,cal(λ)) by matching the measured spectral intensity distribution (M(Sd)) with the spectral transmittance (ΤΕ(λ)) of the etalon (50).

    Abstract: Embodiments of the present invention provide a Raman spectroscopic inspection method, comprising the steps of: measuring a Raman spectrum of an object to be inspected successively to collect a plurality of Raman spectroscopic signals; superposing the plurality of Raman spectroscopic signals to form a superposition signal; filtering out a florescence interfering signal from the superposition signal; and identifying the object to be inspected on basis of the superposition signal from which the florescence interfering signal has been filtered out. By means of the above method, a desired Raman spectroscopic signal may be acquired by removing the interference caused by a florescence signal from a Raman spectroscopic inspection signal of the object. It may inspect correctly the characteristics of the Raman spectrum of the object so as to identify the object effectively.
