Abstract: The invention relates to a method for detecting at least one chemical compound V that is contained in a medium (312). Said method has a verification step (420), in which the presence of the compound V in the medium (312) is determined. In addition, the method has an analysis step (424), in which a concentration c of the chemical compound or compounds V is determined. The verification step comprises the following sub-steps: (a1) the medium (312) is irradiated with first analysis radiation (316) of a variable wavelength λ, said wavelength λ having at least two different values; (a2) a spectral response function A(λ) is generated using the radiation (324) that has been absorbed and/or emitted and/or reflected and/or scattered by the medium (312), in response to the first analysis radiation (316); (a3) at least one spectral correlation function K(δλ) is formed by comparing the spectral response function(s) A(λ) with at least one model function R(λ + δλ), in which said model function(s) R(λ) represent(s) a spectral measured function of a medium (312) that contains the chemical compound V and δλ is a co-ordinate shift; (a4) the spectral correlation function(s) K(δλ) is examined in a model identification step (418) and conclusions are drawn as to whether the chemical compound(s) V is or are contained in the medium (312). The analysis step (424) has the following sub-steps: (b1) the medium (312) is irradiated with at least second analysis radiation (318) that has at least one excitation wavelength λEX; (b2) at least one spectral analysis function B(λEX, λRES) is generated using the radiation (326) of the response wavelength λRES that has been absorbed and/or emitted and/or reflected and/or scattered by the medium (312), in response to the second analysis radiation (318) of wavelength λEX and conclusions concerning the concentration c are drawn.

Abstract: A detector for optical detection of an object contains a modulation device generating at least one modulated light beam from the object to the detector; a longitudinal optical sensor having at least one sensor region and designed to generate at least one longitudinal sensor signal depending on an illumination of the sensor region by the modulated light beam; and an evaluation device designed to generate at least one item of information on a longitudinal position of the object. The longitudinal sensor signal contains a first component, which depends on a response of the longitudinal optical sensor to a variation of the modulation of the modulated light beam, and a second component, which depends on the total power of the illumination. The item of information is generated by deriving the first component and the second component from the longitudinal sensor signal.
