    Abstract: An electron microscope (10) is adapted to enable spectroscopic analysis of a sample (16). A parabolic mirror (18) has a central aperture (20) through which the electron beam can pass. The mirror (18) focuses laser illumination from a transverse optical path (24) onto the sample, and collects Raman and/or other scattered light, passing it back to an optical system (30). The mirror (18) is retractable (within the vacuum of the electron microscope) by a sliding arm assembly (22).

    Abstract: A curved mirrored surface (78) is used to collect radiation scattered by a sample surface (76a) and originating from a normal illumination beam (70) and an oblique illumination beam (90). The collected radiation is focused to a detector (80). Scattered radiation originating from the normal and oblique illumination beams may be distinguished by employing radiation at two different wavelengths, by intentionally introducing an offset between the spots illuminated by the two beams or by switching the normal and oblique illumination beams (70, 90) on and off alternately. Beam position error caused by change in sample height may be corrected by detecting specular reflection of an oblique illumination beam and changing the direction of illumination in response thereto. Butterfly-shaped spatial filters may be used in conjunction with curved mirror radiation collectors (78) to restrict detection to certain azimuthal angles.

    Abstract: There is provided an imaging device for wavelength dependent imaging, comprising:
    a detector comprising a plurality of light sensitive elements;
    a plurality of light propagating units, each comprising:
    a funnel element for collecting light at a collecting end and propagate the light to a transmitting end;
    a waveguide for receiving light from the transmitting end at a receiving end and propagating light to a distributing end.


    Propagation of light through the waveguide is dependent on wavelength, thus light at the distributing end is distributed dependent on wavelength.
    For a first and second light propagating unit the funnel element and the waveguide have a first and second asymmetric coupling respectively, thus the central funnel axis at the transmitting end has a first and second displacement from the central waveguide axis at the receiving end, respectively.
    Each light propagating unit is arranged such that light at the distributing end is incident onto at least two light sensitive elements.

    Abstract: Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum optischen Erkennen unterschiedlicher Objekte mit einer Sensoreinheit zur elektromagnetischen Detektion der Objekte auf einer landwirtschaftlichen Fläche, wobei die Sensoreinheit mindestens eine Strahlungsquelle zur Beleuchtung eines Messflecks und mindestens einen Detektor zur Messung einer Intensität einer Strahlung aus dem Messfleck umfasst, und wobei eine Steuervorrichtung ausgebildet ist, durch die die Strahlungsquelle und der Detektor elektrisch getaktet betreibbar sind. Vor dem Detektor ist eine Filtereinrichtung angeordnet, durch die Strahlungen mit zumindest zwei zueinander verschiedenen Spektralbereichen auswählbar sind, wobei die Strahlungsquelle zumindest einen ersten Sender mit einer ersten Wellenlänge λ1 und einen zweiten Sender mit einer zweiten Wellenlänge λ2 umfasst. Dabei ist eine Auswerteeinheit dazu ausgebildet, aus von dem Detektor gemessenen Werten der Intensitäten, die beim Bestrahlen mit den verschiedenen Wellenlängen auftreten, ein Verhalten des Reflexionsgrades des Objekts in dem Messfleck zu bestimmen.

    Abstract: A light source for near-infrared transmission and reflection spectroscopy can be constructed from a combination of a high power blue or blue-green light emitting diode (LED) and a phosphor element based on an inorganic material. The phosphor element absorbs the LED light and, in response to the LED excitation, emits luminescence that continuously covers the 700-1050 nm range. One possible material that can be used for such a near-infrared emitting phosphor element is a single crystal rod of Ti+3 doped Sapphire. An alternative near-infrared emitting phosphor material is a disk or rectangular shaped composite of Ti+3 doped Sapphire powder embedded in a clear optical epoxy or silicone encapsulant. Such a combination of a blue LED for excitation of a phosphor element that emits in a broad wavelength band has been widely used in white LEDs where the emission is in the 400-700 nm range.

    Abstract: Systems and methods for remote and/or portable detection are provided. The system can include a source (305) of coherent laser pulses, components (315,320) for converting the coherent laser pulses into first beam pulses (391) at a first wavelength value, second beam pulses (392) at a second wavelength value, and third beam pulses (393) at a third wavelength value. Systems can further include optical components (330) configured to delay at least one of the first beam pulses, the second beam pulses, and the third beam pulses in order to create delayed beam pulses, and a focusing component (340) configured direct a substantially collinear combination of the delayed beam pulses and two of a set of: the first beam pulses, the second beam pulses, and the third beam pulses, onto a sample (355).

    Abstract: The invention relates to a method and a light source device for supplying light to illuminate an object. A light array comprising LED units that are arranged adjacently to one another and emit light of different wavelength ranges is linearly shifted such that said LED units are selected one after another, each selected LED unit is switched on, the light emitted by each switched-on LED unit is focussed on a linearly shiftable filter, and said linearly shiftable filter is shifted such that, out of the light incident on the filter, it is light with a smaller wavelength range that passes through.
