摘要： A method and a device suitable for carrying out said method of analysis and quantification of flows are disclosed, in particular, for three-dimensional determination of flow-rate components, or the three-dimensional visualisation of flows in fluids or gases. To this effect electromagnetic waves are used, in particular, light, which is partly emitted or scattered by particles (30, 31, 32, 33, 34, 35), which are contained in a detection chamber (25) and which characterise the flow to be analysed. The flow is determined, by detecting the above particles, by means of at least one detection device, in the form of two-dimensional frequency selectively-, or frequency band selectively-taken images (40, 41, 42, 43). An illumination device generates the at least two, consecutive, at least approximately parallel light planes (19, 18, 17, 20, 21, 22) spatially arranged one behind the other, using electromagnetic waves of varying frequency, or differing frequency spectrum, which at least partly scan the detection chamber.(25)

摘要： The subject of the invention is a method and a device for determining the speed of light-scattering objects such as molecules, small particles or the like, at least one light beam being directed onto the scattering centre (10), being scattered there and scattered light (36) being recorded by means of at least one detector (20). Such a method is normally termed Doppler laser anemometry. The known methods operate with a single-colour laser, or only one colour is used for measurement, either the laser beam being split into two beams and a reference beam being split off, or, instead, two beams scattered in different directions being brought into superimposition. In any case, an expensive optical system having, inter alia, beam splitters is required, and these produce sources of error. For the purpose of improvement and simplification, it is proposed to direct light of at least two wavelengths ( lambda 1, lambda 2) from a multicolour laser (12) onto the scattering centre (10) without splitting.

摘要： PCT No. PCT/DE94/00653 Sec. 371 Date Mar. 25, 1996 Sec. 102(e) Date Mar. 25, 1996 PCT Filed Jun. 9, 1994 PCT Pub. No. WO95/01572 PCT Pub. Date Jan. 12, 1995A process and apparatus are disclosed for generating object traces representing the movement of objects through a measuring space. The measuring space can be illuminated by a laser or other light source, or alternatively the objects can be self-illuminating. In either event, light from the objects is detected over a finite acquisition time, to generate the object traces. During a predetermined portion of the acquisition time, preferably near the end, one of several parameters that govern the object trace width is altered to increase the width, thereby giving the object trace the form of an arrow or vector. The altered parameter can be the brightness of illumination, the sensitivity of the image detector, or the position or state of system components, in particular the image detector, a lens or other active optical component between the objects and the detector, or an optical component between the light source and the objects.

摘要： The measuring system uses a controlled variation in the velocity of the flow stream in which the particles are contained, over a defined zone, with measurement of the particle velocity at one or more points within or in front of this zone. Pref. the flow stream is supplied to a closed flow channel with a variation in its dia. used to provide the required velocity variation, the particle velocity determined by a measuring device, eg. a laser doppler anemometer (7, 8), which is movable along the channel.
