Abstract: A spectrometer (11) recognizes a measurement target on the basis of the spectral data set of observed light detected by a spectral sensor (14) capable of measuring wavelength information and light intensity information. The spectrometer is provided with a spectral data processor (16). Spectral data sets are detected at two different positions by the spectral sensor, and the processor subtracts a first spectral data set from a second spectral data set, or divides the first spectral data set by the second spectral data set to calculate one phase correlation spectral data set, which is correlated to the spectral data sets at the two different positions. The processor simultaneously identifies the measurement target corresponding to the two different positions on the basis of the correlation spectral data set.

Abstract: The present invention relates to a method and to a device for generating and for detecting a Raman spectrum. The aim of the present invention is to provide a method and a device for generating and for detecting a Raman spectrum, which enable an automated, or automatable, and at the same time quantitative SERD spectroscopy (for example concentration measurement series). To this end, during the SERD spectroscopy, a first spectrum (16) and a second spectrum (17) are standardized in relation to one another in terms of intensity values and a first difference spectrum (D1) is subsequently calculated, a second difference spectrum (D2) is calculated, the first difference spectrum (D1) is converted into a first transformation spectrum (K1), the second difference spectrum (D2) is converted into a second transformation spectrum (K2), and the Raman spectrum (R1) is calculated by adding the first transformation spectrum (K1) and the second transformation spectrum (K2).

Abstract: A spectroscopic analyzer includes a first measurement section (40) which measures a spectrum of near-infrared region by irradiating a sample with near-infrared light, a second measurement section (30) which measures a spectrum of infrared region by irradiating the sample with infrared light, and an analysis section which analyzes characteristics of the sample using the spectra measured by the first and second measurement sections. The analysis section includes a first calculation module which acquires a integrated spectrum by combining the spectrum of near-infrared region and the spectrum of infrared region, a second calculation module which calculates a difference spectrum of a reference spectrum measured in advance and the integrated spectrum, and a third calculation module which calculates correlation between the spectrum of near-infrared region and the spectrum of infrared region by performing a two-dimensional correlation operation using the difference spectrum.

Abstract: A method of detecting a target gas includes the step of traversing a target area with a gas-filter correlation radiometer having a field of view oriented towards the target area. The gas-filter correlation radiometer receives reflected radiation in a passband from the target area and produces gas-filter correlation radiometer signals from the received reflected radiation. A surface reflectivity spectral profile of the target area is determined. The presence of the target gas in the target area is then determined based upon the received reflected radiation and the surface reflectivity spectral profile of the target area.

Abstract: The invention relates to a method of determining the autocorrelation function g( tau ) of an optical signal. The inventive method comprises the following steps consisting in: determining the instants (ti) at which the photons appear; for a pre-determined set of pulses (w), calculating function s(w) = Si e , wherein e = coswti + sinwti, the summation being performed on all of the pulses received; determining the square S(w) of the modulus of function s(w); and calculating the Fourier transform g( tau ) of the power spectrum S(w) for a pre-determined set of temporal variation values.

Abstract: A method for characterizing fluorescent molecules or other particles in samples comprising the steps of: a) monitoring fluctuating intensity of fluorescence emitted by the molecules or other particles in at least one measurement volume of a non-uniform spatial brightness profile by measuring numbers of photon counts in primary time intervals by a single or more photon detectors, b) determining at least one distribution of numbers of photon counts, P(n), from the measured numbers of photon counts, c) determining physical quantities characteristic to said particles by fitting the distribution of numbers of photon counts P(n), wherein the fitting procedure involves calculation of a theoretical distribution function of the number of photon counts P(n) through its generating function, defined as (I).
