Abstract: Disclosed is a method for measuring the absorbance of light of a substance in a solution in a measuring cell (23; 223′), said method comprising the steps of: transmitting (S1) a first light beam (27; 27′) from a light source (25; 25′) towards a beam splitter (29; 29′); dividing (S3) the first light beam (27; 27′) into a signal light ray (31; 31′) and a reference light ray (33; 33′) by the beam splitter (29; 29′); modulating (S5) the signal light ray (31; 31′); modulating the reference light ray (33; 33′); providing (S9) the measuring cell (23; 23′) such that the signal light ray (31; 31′) passes through the measuring cell; detecting (S11) a signal in a detector (39; 39′), which signal is the combined signal intensity of the signal light ray (31; 31′) and the reference light ray (33; 33′) detected by the detector (39; 39′); performing synchronous detection (S15) of the detected signal in order to reconstruct the intensities of the signal light ray (31; 31′) and the reference light ray (33; 33′) from the combined signal detected by the detector (39; 39′), said synchronous detection being based on the modulation performed to the signal light ray and the reference light ray. Disclosed also is a measuring device for carrying out said method.

Abstract: A system and method for determining the pH value of a liquid. The system and method excite the liquid molecules in the liquid by light with a predetermined wavelength and an intensity component, transmitted through the liquid in a predetermined wavelength range, of the light used for excitation is captured. This intensity component is used to produce a wavelength/intensity absorption characteristic and this absorption characteristic is related to a reference absorption characteristic associated with a specific pH value of the liquid. The system and method thus can be used to obtain drinking water from a fuel for aircraft.

Abstract: A multi-channel source assembly for downhole spectroscopy has individual sources that generate optical signals across a spectral range of wavelengths. A combining assembly optically combines the generated signals into a combined signal and a routing assembly that splits the combined signal into a reference channel and a measurement channel. Control circuitry electrically coupled to the sources modulates each of the sources at unique or independent frequencies during operation.

Abstract: An apparatus for determining element occupancy on a surface includes a UV beam source comprising at least one UV light-emitting diode whose UV radiation excites the element to fluorescence and a detector unit for the detection of fluorescence radiation. The apparatus, in accordance with the invention, is characterized in that beam guidance is configured by alignment of the UV beam source and the detector unit relative to the surface and/or by using a wavelength-selective beam splitter in the beam path in such a manner that the UV radiation back-reflected from the surface is kept away from the detector unit.

Abstract: The invention relates to a method and a microelectronic sensor device for making optical examinations in an investigation region (3). An input light beam (L1) is emitted by a light source (20) into said investigation region (3), and an output light beam (L2) coming from the investigation region (3) is detected by a light detector (30) providing a measurement signal (X). An evaluation unit (40) provides a result signal (R) based on a characteristic parameter (e.g. the intensity) of the input light beam (L1) and the output light beam (L2). Preferably, the input light beam (L1) is modulated with a given frequency (ω) and monitored with a sensor unit (22) that provides a monitoring signal (M). The monitoring signal (M) and the measurement signal (X) can then be demodulated with respect to the monitoring signal, and their ratio can be determined. This allows to obtain a result signal (R) that is largely independent of environmental influences and variations in the light source.

Abstract: Nitrogen-containing compounds are detected by chemically converting (210) them to nitrogen dioxide, and detecting (10) the amount of nitrogen dioxide. A semiconductor laser or light emitting diode (132) provides a modulated light (131) in the blue-violet-green wavelength range and a narrow bandwidth photo-acoustic sensor (10) detects the standing waves produced by the absorption of the light by the nitrogen dioxide. The photo-acoustic sensor (10) uses a resonant cavity (161, 182a-b) with a resonant frequency that corresponds to the modulation frequency of the light (131). For detecting nitric oxide, a surface chemical oxidation unit (210) is preferably used to convert the nitric oxide to nitrogen dioxide, using, for example potassium permanganate (KMnO4) filter, or a platinum (Pt) catalyst unit (260).

Abstract: A method and apparatus for automatically selecting test types for an analytical meter system based on the insertion into the meter of a test element. The test element can be an analytical element, formed by a test strip with a fluid such as blood applied thereto; a control element, formed by a test strip with control fluid applied thereto; or a standard element, or a standard strip exhibiting known optical properties. By inserting the test element into the analytical meter system, optical properties are measured and the existence of relationships between the measurements are ascertained. Based on the existence or nonexistence of certain relationships, the proper test can be automatically selected by the meter without the need for user interaction. Advantageously, the results of the test can be classified and stored according to test type.

Abstract: The subject invention detects the presence of an ozone reducing coating on an automotive radiator of the type having spaced fins presenting electromagnetic surface properties different than the electromagnetic surface properties of the coating. In accordance with the subject invention light rays are emitted or reflected off the coating on the fins to a detector and a comparator compares these light rays to a predetermined benchmark to provide a signal in response to the detected light rays crossing the benchmark. In a species, a second detector is employed to detect rays from an un-coated section to establish the benchmark.
