  • Patent number: 9841380
    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.

  • Patent number: 9448167
    Abstract: A measurement device and method for the detection of airborne particles. The device includes a nozzle designed to produce a laminar flow of air with a flow path beyond the nozzle, a first laser and a second laser being positioned for emitting time-amplitude modulated laser light with intersecting laser beams with a laser beam intersection region in a region of the air flow path, and two photodetectors positioned for the detection of laser light scattered in the laser beam intersection region by airborne particles contained in the laminar air flow. The lasers are designed for emission of time-amplitude modulated laser light of identical laser emission wavelength, and the photodetectors are positioned and designed each for the detection of scattered laser light from both lasers.

  • Patent number: 8514378
    Abstract: A method and device for optical teledetection of compounds in a medium includes a detection measurement carried out by emitting into the medium, short pulses of light at least 3 nm wide, and detecting a part of the light back-scattered by the medium by means of a detection unit with temporal resolution. A reference measurement in which the light emitted or the light back-scattered is filtered by virtue of addressable filters, simulating the optical spectrum of the light at the working wavelengths of at least one given compound to be searched for. A comparison of the detection and reference measurements is made to deduce therefrom the possible presence of the compound or compound(s) searched for in the medium. The addressable filters are modified dynamically, and a series of reference measurements and corresponding comparisons are performed for a series of various compounds liable to be present in the medium.

  • Patent number: 8097830
    Abstract: The invention relates to a method for material processing and/or material analysis of an object (18) made from condensed matter by means of a laser (12). A laser pulse (14) is generated by a laser, emitted in the direction of the object. The laser pulse is spatially and temporally focussed such as to give a peak power for the laser pulse at a point between the laser and the object which exceeds the critical power for a self-focussing effect of the laser pulse. The laser pulse thus forms a filament (88) of high power density. The filament (88) is directed at the object and generates an aggregation state change there (evaporation or plasma formation) for a part of the material of the object. The method can be applied to both material processing (cutting, drilling, welding, hardening) and material analysis (analysis of the plasma light).
