Abstract: The present disclosure describes a Lambertian gas-sensing system that may enable gas sensing in a compact form factor. The Lambertian gas-sensing system may include a hollow cavity, one or more light-emitting diode (LED) illuminators, one or more light- absorption detectors, and a gas exchange manifold. The hollow cavity may mechanically integrate the gas exchange manifold, the one or more LED illuminators, and one or more light-absorption detectors (such as one or more optical detectors). The gas exchange manifold may introduce gas into the hollow cavity and the one or more LED illuminators may emit light into the hollow cavity through one or more ports. The one or more light- absorption detectors may receive light from the hollow cavity through one or more ports.

Abstract: Beschrieben werden eine Spektroskopie-Vorrichtung sowie ein Verfahren zur Bestimmung von Blutparametern in nicht-hämolysierten Blutproben (5) mit wenigstens einer Lichtquelle (1) zur Emission von Strahlung im Wellenlängenbereich zwischen 300 nm und 1000 nm, mit einer während einer Messung die Blutprobe aufnehmenden Messküvette (4), die wenigstens in einem Messbereich, durch den die Strahlung wenigstens zeitweise während der Messung hindurchtritt, optisch transparent ist, mit einem Integrator (6) zum Empfang des von der durchstrahlten Blutprobe (5) vorwärts gestreuten Lichts und mit einem Spektrometer (8), dem die vom Integrator (6) empfangene Strahlung zugeleitet wird und durch das ein Messignal auf der Grundlage wenigstens einer Eigenschaft der Strahlung erzeugbar und an eine Datenverarbeitungseinheit zur Auswertung mittels eines prädiktiven Modells (12) übertragbar ist.

Abstract: Methods of deep ultraviolet fluorescence (DUVF) and multi spectral imaging (MSI) detection are disclosed herein for the detection and identification of pathogens on plants. DUV light and visible or near- infrared light are used to illuminate plants or plant leaves such that the light intensity reflected or emitted by the plant or plant leaves can be used to identify the type of pathogen and measure the amount of pathogen on the plant or plant leaves and, additionally, be used to measure the plant's stress response to such pathogen. Also provided herein is a biophotonic analyzer device (10) that uses both DUVF and MSI detection for the monitoring and surveillance of plant health and for the identification and enumeration of pathogens on plants or plant leaves (65).
