    摘要： Methods and apparatus, including computer program products, implementing and using techniques for collecting optical data pertaining to one or more characteristics of a sample. The apparatus has a light source, one or more illumination optical elements, a scanner, one or more collection optical elements, and a device forming an aperture that limits detection of light from the sample. The illumination optical elements direct a light beam from the light source onto the sample. The scanner scans the light beam across the sample. The collection optical elements collect light from the sample and transmit the collected light to a detector. None of the collection optical elements are included among the illumination optical elements. The device forming an aperture limits detection of light from the sample to light associated with a limited vertical depth within the sample, and is one of the collection optical elements.

    摘要： The present invention reduces the influences of electromagnetic fields during reading out of image signals from memory phosphor films. This is done by pre-amplifying the detection signals obtained from a detection device, in particular a CCD array, before further processing, for example by an analog-to-digital converter. An amplification register for electron multiplying can be used for the amplification. In this way individual photon sensitivity can be achieved when reading out X-ray images.

    摘要： A lighting element with a gaseous tritium light source and an elongated plastic housing that at least partially encloses the gaseous tritium light source with its housing shell and forms a latching element that snaps together with the gaseous tritium light source, which can be inserted into the plastic housing, and holds it in the plastic housing. A rugged lighting element can be produced if the latching element is formed by at least one catch element, which catch element has a radially sprung flexible spring and at least one, preferably two, inwardly oriented snaps with an indentation for snapping together with the gaseous tritium light source.

    摘要： An apparatus for and method of performing multi-photon light sheet microscopy (MP-LISH), combining multi-photon excited fluorescence with the orthogonal illumination of light sheet microscopy are provided. With live imaging of whole Drosophila and zebrafish embryos, the high performance of MP-LISH compared to current state-of-the-art imaging techniques in maintaining good signal and high spatial resolution deep inside biological tissues (two times deeper than one-photon light sheet microscopy), in acquisition speed (more than one order of magnitude faster than conventional two-photon laser scanning microscopy), and in low phototoxicity are demonstrated. The inherent multi-modality of this new imaging technique is also demonstrated second harmonic generation light sheet microscopy to detect collagen in mouse tail tissue. Together, these properties create the potential for a wide range of applications for MP-LISH in 4D imaging of live biological systems.

    摘要： A device for illuminating flat carriers in accordance with the invention, characterized by the fact that the light produced by a radioactive light source is radiated upon the carrier consisting of a transparent material, the radiated light being totally reflected by a part of a main surface of the carrier, one main face of the carrier being adapted to reflect or disperse light at areas where markings appear, or at any areas other than those of the markings, in order to allow the light which is reflected or dispersed at these areas to escape through the other main face of the carrier.
