Abstract:
A sensor module (1) for measuring the distance to a target and/or the velocity of the target (50), the sensor module (1) comprising at least one laser source (100), at least one detector (200) being adapted to detect modulated laser light and at least one control element the control element (400) being adapted to vary the focus point ofthe laser light and/or the intensity of the laser light and/or the direction of the laser light. The controlofthe laser light emitted by the laser source (100) either by active optical devices as variable focus lenses or controllable attenuators or passive optical elements in combination with arrays of laser sources (100) and detectors (200) enable flexible and robust sensor modules.

Abstract:
A sensor device is described being designed to detect the phasetransition ofat least a part of a test material from the solid phase to the liquid phase. The sensor device comprises a light source (1) for initiating the phase transition for example by heating up the test material (10) by means of the emitted transition light (7). Further, the sensor device comprises a light detector (8) detecting detection light (6) thrown back by the solid phase of the test material (10) and subsequently detection light (6) thrown back by the liquid phase of the test material (10) afterat least a part of the test material (10) is melted by the transition light (7). The comparison of the signals received by the light detector (8) enables the detection of a phase transition of the test material (10) heated up by means of the light source (10). Examples of test materials (10) are ice and fat. Possible applications are the detection of ice in the automotive or aircraft industry.

Abstract:
The invention relates to a low-pressure gas discharge lamp, that comprises at least a gas discharge vessel (2) that contains a gas filling having a copper, indium, thallium or gallium compound selected from the group consisting of the halides, oxides, chalcogenides, hydroxides, hydrides, or the organometallic compounds, or the tin halides, or the chalcogenides of the main group 4 of the periodic table, or mixtures thereof, and that contains a buffer gas, and components for producing and maintaining a low-pressure gas discharge (3), the gas discharge vessel (2) having at least one region that serves primarily as an exit opening (4) for the molecular radiation of a predetermined wavelength range and a predetermined radiation density that is emitted, which radiation density, when the lamp (1) is operating, is increased in comparison with the radiation density at the other regions of the gas discharge vessel (2) at which radiation can, in principle, emerge.

Abstract:
A discharge lamp comprising a light-transmitting discharge vessel enclosing, in a gas-tight manner, a discharge space comprising a mercury- free fill, the mercury- free fill comprising a molecular radiator compound, selected from the group of metal halides of ruthenium(III), osmium(III,IV), rhodium(III) and rhenium(III), wherein the halide is selected from the group of chloride, bromide and iodide and combinations thereof, and a buffer gas for aiding in starting and buffering the discharge, the discharge lamp further comprising discharge means for igniting and maintaining a discharge in the discharge space emits radiation in the visible range as well as possibly in the UVA range. The visible radiation spectrum is of the cold- white type, while radiation in the UV range is reduced in comparison to mercury-dosed lamps. Losses in visible light, e.g. by Stokes' shift, are thereby reduced and less energy is wasted by radiative output in the ultraviolet. Another advantage of this lamp technology is that it does not require the use of mercury vapor, which is an environmentally hazardous material with known human toxicity. It is therefore environmentally safe.
