摘要： A method for monitoring a manufacture of wood-based products includes at least one pressing process with regard to the emission of volatile organic compounds from the wood-based products, in which the concentration of the volatile organic compounds is detected during the manufacture. The concentration of the volatile organic compounds is detected during an extraction of product parts or of a product surface using a measurement method from the field of TDLS (Tunable Diode Laser Spectroscopy), FTIR, NIR, IMS or photoacoustics, that the detected concentration of the volatile organic compounds is fed to a mathematical model, and that parameters such as product thickness, areal density, production feed rate, flow rate in an extraction of product parts or of the product surface and the moisture content of the raw materials for the wood-based products are determined before the pressing process and are also fed to the mathematical model.

摘要： Optical cells are described for use in spectroscopy applications. The cells include a series of discrete planar reflectors aligned with one another and spaced apart from one another at each end of the sample cavity. The discrete planar reflectors can be surrounded by transparent windows and divergent energy can be removed from the cell cavity via the windows. The cells can define a unique beam path for the energy beam, and there can be no overlapping optical paths through the cell. The cells can provide well-defined detection signals with very high signal-to-noise ratio.

摘要： A method for studying cell viability and protein aggregation involves establishing a Fabry Perot etalon signal within an optical spectroscopic feature, e.g., in the near infrared region. Protein aggregation and cell viability can be reflected by changes observed in the magnitude of the Fourier Transform peaks observed in the frequency or space domain associated with the contrast of the etalon. In short, the presence of viable cells and protein aggregates can degrade the etalon contrast of an etalon window. In some cases, the concentration of cells and monomeric protein can be measured as well.

摘要： An interferometric fluid sensing system includes: a laser; a plurality of first fibre portions arranged to receive laser light from the laser; a second fibre portion configured to provide a reference arm for the interferometric fluid sensing system; and a detector arranged to receive light from the first and second fibre portions, wherein the laser light that passes through a void of each first fibre portion is caused to interfere with light passing through the second fibre portion at or before reaching the detector, wherein each of the first fibre portions is arranged such that that light passing through the void of each first fibre portion travels from the laser to the detector over a different path length from the light passing through the voids of the other first fibre portions.

摘要： An optical system comprises a wearable device for measuring one or more physiological parameters. The physiological parameters may change in response to stretching of the hand or movement of fingers or thumb of the user, or the parameters may be related to blood constituents or blood flow. The wearable device comprises a light source with a plurality of semiconductor diodes and a detection system that measures reflected light from tissue comprising skin. The semiconductor diodes may be light emitting diodes or laser diodes. The signal to noise ratio for the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity of at least one of the plurality of semiconductor diodes from an initial light intensity, and using change detection that compares light on versus light off for the detection system output. The wearable device is also configured to identify an object.
