The method comprises a verification step (420) which is used to determine whether V is contained in the medium (312). The method furthermore comprises an analysis step (424) in which a concentration c of the at least one chemical compound V is determined.The verification step comprises the following substeps: (a1) the medium (312) is exposed to a first analysis radiation (316) of a variable wavelength λ, the wavelength λ assuming at least two different values; (a2) at least one spectral response function A(λ) is generated with the aid of the radiation (324) 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 spectral comparison of the at least one spectral response function A(λ) with at least one pattern function R(λ+δλ), the at least one pattern function R(λ) representing a spectral measurement function of a medium (312) containing the chemical compound V and δλ being a coordinate shift; (a4) the at least one spectral correlation function K(δλ) is examined in a pattern recognition step (418), and a conclusion is made as to whether the at least one chemical compound V is contained in the medium (312); The analysis step (424) comprises the following substeps: (b1) the medium (312) is exposed to at least one second analysis radiation (318) having at least one excitation wavelength λEX; (b2) at least one spectral analysis function B(λEX,λRES) is generated with the aid of the radiation (326) of the response wavelength λRES absorbed and/or emitted and/or reflected and/or scattered by the medium (312) in response to the second analysis radiation (318) of the wavelength λEX and the concentration c is deduced therefrom.

Abstract: A remote sensing method for detecting and analyzing gases, vapors and flame plumes using an imaging spectrometer. The spectrometric instrument uses Image Multispectral Sensing (IMSS) technology, enhanced by advanced imaging processing techniques and micro-miniature circuitry. These enhancements provide a portable instrument with the capability to remotely detect and image gases, including gas leaks. The technology also provides an analysis of the gas including chemical species and concentrations. The instrument can also remotely detect, image and analyze flames and plumes in the same manner, providing an analysis of the chemical species and concentrations in the flame. Advanced image processing techniques are used to provide gas and plume images and analysis to the operator. These processing algorithms are implemented in micro-miniature circuits such as digital signal processors (DSP's) and field programmable gate arrays (FPGA's) to provide a field portable instrument.

Abstract: In the procedure, the light beams are incident parallel to the transparent medium and are deflected toward a focal point inside the transparent medium. This avoids the use of refractive lens systems. The focusing lens system according to the invention enables the bundling of light beams of different wavelength to a point inside the sample. This clearly simplifies the design and adjustment of a multicolor fluorescence correlation spectroscopy device.

Abstract: A spectrometer (10) includes a two-dimensional array of modulatable micro-mirrors (18), a detector (20), and an analyzer (22). The array of micro-mirrors is positioned for receiving individual radiation components forming a part of an input radiation source. The micro-mirrors are modulated at different modulation rates in order to reflect individual radiation components therefrom at known and different modulation rates. The micro-mirror array combines a number of the reflected individual radiation components and reflects the combined components to the detector. The detector is oriented to receive the combined radiation components reflected from the array and is operable to create an output signal representative thereof. The analyzer is operably coupled with the detector to receive the output signal and to analyze at least some of the individual radiation components making up the combined reflection. By using a micro-mirror that receives individual radiation components and then modulates the radiation components at different rates, all of the radiation components can be focused onto a single detector to maximize the signal-to-noise ratio of the detector. A variable band pass filter spectrometer, variable band reject filter spectrometer, variable multiple band pass filter spectrometer, and a variable multiple band reject filter spectrometer utilizing the same invention are also disclosed.

Abstract: A grating spectrometer employing digital control of an oscillating component (a mirror) and phase-locked digital recording of the intensity profile within the narrow spectral domain defined by an oscillation frequency. Flexible choice of oscillation frequency permits measurement in a quiet region of the noise spectrum. Reference waveforms acquired with the same insturment can be stored and later used to deconvolute a more complex spectrum. The use of multiple detector/slit combinations along a Rowland circle makes the spectrometer sensitive to specific atomic elements.
