Abstract: A system and method to discriminate between a first preselected gas and at least one other preselected gas use of an absorption spectroscopy analyzer that includes a Herriott cell and a temperature sensitive light source. The light source operates at a temperature that emits a beam at a wavelength that corresponds to high absorption by a first preselected gas. When a predetermined level of this gas is detected in a gas sample, the analyzer changes the operating temperature of the light source to emit a beam at a wavelength that corresponds to high absorption by a second preselected gas. The second preselected gas can be a different isotope of the first preselected gas.

Abstract: A light radiating portion radiates light with wavelength λ1 having predetermined absorptivity for an object and light with wavelength λ2 having smaller absorptivity for the object than the wavelength λ1, to a target, so as to scan in 2-dimensional directions. A light receiving portion receives scattered lights reflected by the target based on light with wavelength λ1 and light with wavelength λ2. A measuring portion generates information used for detection of the object at the target, based on difference between the two scattered lights with wavelength λ1 and wavelength λ2 received by the light receiving portion. An output portion outputs whether or not the object is present at the target, by 2-dimensional area information, based on scanning by the light radiating portion and information generated by the measuring portion.

Abstract: NDIR is used to determine a concentration of a chosen molecule M in a liquid sample which contains one or more interfering molecules MJ which absorb radiation at the signal wavelength used in the NDIR process by addition of an interference source. M is calculated by electronics which use Rave(t) from a pulsed signal and reference channel output and a calibration curve which is validated by use of RJave(t2) from a pulsed interference and reference channel output. Signal, interference and reference sources are pulsed at a frequency which is sufficiently fast so that a given molecule of M or MJ will not pass in and out of the liquid sampling matrix within the pulsing frequency.

Abstract: Methods and systems for performing simultaneous spectroscopic measurements of semiconductor structures at ultraviolet, visible, and infrared wavelengths are presented herein. In another aspect, wavelength errors are reduced by orienting the direction of wavelength dispersion on the detector surface perpendicular to the projection of the plane of incidence onto the detector surface. In another aspect, a broad range of infrared wavelengths are detected by a detector that includes multiple photosensitive areas having different sensitivity characteristics. Collected light is linearly dispersed across the surface of the detector according to wavelength. Each different photosensitive area is arranged on the detector to sense a different range of incident wavelengths. In this manner, a broad range of infrared wavelengths are detected with high signal to noise ratio by a single detector. These features enable high throughput measurements of high aspect ratio structures with high throughput, precision, and accuracy.

Abstract: This invention concerns the field of sample identification, in particular a method and apparatuses for identifying or discriminating biological species from non biological species, both as individual particles and as components of a composition, by pump-probe fluorescence spectroscopy for time-resolved detection or imaging. The method uses the finding that the UV-induced fluorescence of biological molecules is varied, in particular is depleted, by the addition of visible radiation, whereas this does not occur with non-biological organic molecules. The invention discriminates the fluorescence signals of bio and non-bio particles or species using a differential approach, i.e. the comparison. of the total fluorescence recorded with and without additional visible radiation. This allows to discriminate biological particles comprising aromatic amino-acids (AA), like peptides, proteins, bacteria, viruses, pollens, spores, etc., from non-biological particles, like aromatic (AH) or polyaromatic hydrocarbons (PAH), carbonaceous aerosols, soot, etc.

Abstract: The present invention concerns a method and system for gas concentration measurement of gas or gas mixtures dissolved in liquids. A gas or gas mixture dissolved in a liquid sample is extracted from the liquid sample using an extraction system and conducted into a measurement chamber. Then a measurement signal is generated by means of a radiant source and the measurement signal is directed to a measurement object in a measurement chamber containing the gas or gas mixture to be measured. The measurement signal is filtered using at least two wavelengths, whereupon the filtering is preferably implemented by means of an electrically tunable, short-resonator Fabry-Perot interferometer. Then the filtered measurement signals are detected my means of a detector.

Abstract: Systems and methods for measuring a target in a sample, the target being capable of generating an emitted light in response to an excitation light. In an example system, an excitation light source generates the excitation light along an excitation optical path. An attenuation filter arrangement selectively adds an attenuation filter to the excitation optical path. The attenuation filter attenuates the excitation light by a corresponding attenuation factor. The excitation light exits the attenuation filter arrangement along the excitation optical path to illuminate the sample. A light energy detector receives the emitted light generated in response to the excitation light, and outputs a measured signal level corresponding to an emitted light level. If the light energy detector indicates an overflow, signal measurement is repeated with attenuation filters of increasing attenuation factors until the measured signal level does not overflow.

Abstract: Methods and apparatus for article authentication include an exciting radiation generator that exposes an area of the article to exciting radiation, and at least two radiation detectors that detect emitted radiation from the area in a first band and in a second band that does not overlap the first band. The first band corresponds with a first emission sub-band of an emitting ion, and the second band corresponds with a second emission sub-band of the same emitting ion. A processing system calculates a comparison value that represents a mathematical relationship (e.g., a ratio) between a first intensity of the emitted radiation in the first band with a second intensity of the emitted radiation in the second band, and determines whether the comparison value compares favorably with an authentication parameter. When the comparison value compares favorably with the authentication parameter, the article is identified as being authentic.

Abstract: A method for determining a chance to enable a zeroing of gas analysis is disclosed herein. The method includes emitting radiation, and receiving emitted radiation, the received radiation comprising a first wavelength range absorbed by the at least one desired gas component and one or more disturbing factor, and a second wavelength range absorbed by the disturbing factor, the first wavelength range differing from the second wavelength range. The method also includes providing to a processing unit a first signal data indicative of a concentration of the at least one desired gas component and absorption of the disturbing factor, and a second signal data indicative of absorption of the disturbing factor. The method also includes determining a stability of the first and second signal data as a function of time, and if they are substantially stable enabling the zeroing to improve a measurement accuracy.
