Abstract: A shutter assembly includes a first shutter blade having a first toothed arm extending therefrom and a first light transmitting aperture therein, and a second shutter blade positioned adjacent and parallel to the first shutter blade. The second shutter blade has a second toothed arm extending therefrom and a second light transmitting aperture therein. The first and second shutter blades are supported to allow parallel linear motion. A motor gear is disposed between, and meshed with, the first and second toothed arms such that rotation of the gear causes the first and second shutter blades to move linearly in opposite directions between an open position in which the first and second light transmitting apertures are in an overlapping relationship with respect to one another, and a closed position in which the first and second light transmitting apertures are in a non-overlapping relationship with respect to one another.

Abstract: A device for determining the composition of a mixture of fluids that flow along a pipe, which comprises: a radiation source for illuminating the mixture with radiation; a detector for detecting radiation that has been attenuated by the mixture; a device for monitoring the flow rate of fluid along the pipe and outputting a signal indicative of the flow rate. The device includes a device for adjusting the intensity of radiation emitted by the radiation source in response to the signal indicative of the flow rate so that the intensity of the radiation source is reduced if the flow rate reduces.

Abstract: A radiation pulse, such as from a solar simulator, is spectrally analyzed over a selected sampling pulse that is shorter in duration than the radiation pulse and is timed to begin after the start of the radiation pulse. A deformable membrane mirror is controlled to function as a high speed shutter in the path of the radiation pulse. When not deformed, the mirror reflects the radiation pulse into an optical instrument, such as a spectroradiometer. A sampling pulse is generated for a selected time after the start of the radiation pulse and is applied to the mirror to ensure total reflection of the radiation pulse only for the duration of the sampling pulse. Controls are provided to adjust the start time and duration of the sampling pulse, and to adjust the sensitivity of sensing the start of the radiation pulse.

Abstract: At the time of analytical measurement of a sample by the fluorescence measuring device or the phosphorescence measuring device, both the optical path of exciting light emitted from the light source 1 to the sample 6 and the optical path of fluorescence or phosphorescence emitted from the sample to the detection unit 10 are shut off. Both are shut off by one chopper 11, 12.

Abstract: The arrangement has a laser for generating laser-induced plasma in a sample, where the plasma emits light of different wavelengths. A stopper unit (44) is formed by a rotating chopper disk to interrupt the optical paths of the light. The unit has openings (54, 56, 58, 60, 62) through which the light emitted by the plasma is guided. The unit has an opening (70) through which a light sensitive auxiliary detector is illuminated for generating a trigger signal for triggering the laser.
