Abstract: The invention relates to method for imaging measurement of a moving or flowing target and to an imaging measuring device for implementing the aforementioned method. Moreover, the invention relates to the use of information measured by means of imaging measurement in the control and/or adjustment of a process. According to the invention, electromagnetic radiation obtained from the moving or flowing target (T) is focused by means of imaging optics to produce an image to the screen of a two-dimensional matrix detector at least via a first and a second filter (F 1 , F 2 ) which transmit electromagnetic radiation in manners differing from each other. Said at least first and second filter form on the screen of the detector at least a first and a second filter area (FR 1 , R 2 ) that partly cover the light-sensitive area (DA) of the detector. The properties of the target (T) are determined spectroscopically by comparing and/or combining spectrally resolved information, which is recorded when a pixel which corresponds to a determined part of the target kto be measured and is focused on the screen (DA) of the matrix detector without beamsplitting travels under the effect of the movement of the target (T) via said at least first and second filter area (FR 1 , FR 2 ). The area of the screen (DA) of the detector remaining outside siad filter areas (FR 1 , FR 2 ) is used for other kind of imaging non-spectroscopic measurement and/or visualization of the target.

A gas turbine jet propulsion engine comprises a first compressor or ducted fan, a main air compressor, a combustion system, and a turbine system, the first compressor and the main compressor being driven by the turbine system, there being a by-pass duct surrounding the engine and communicating at its upstream end with the outlet of the first compressor. A tubular partition member is provided to divide the by-pass duct into radially inner and outer air passages, a valve being provided to control flow of air through the outer passage, also means for burning fuel so as to heat the air flow through the inner passage. The engine shown comprises a first compressor 10, a main compressor 11, combustion equipment 12, a high pressure turbine 13 which drives the compressor 11 through shaft 15 and a low pressure turbine 14 which drives the first compressor 10 through inner shaft 16. Flow of air from the first compressor 10 is divided into two streams by the flow divider 21, one stream passing into the main compressor 11 and the second stream passing into the by-pass duct 31. The by-pass duct has disposed therein an annular partition member 34 which divides the duct into an inner part 32 and an outer part 33, a series of flap members 38 being pivotally mounted at the upstream end of the partition. The flap members 38 are controlled by actuators 40 and are movable between the position shown at the left-hand side of Fig. 1 in which they close off the upstream end of the outer duct 33 and the position shown at the right-hand side of Fig. 1 in which the upstream end of the outer duct is opened to air flow. Fuel injection devices 35 and flame stabilizers 36 also spark ignition devices 37 are provided in the inner duct 32. For normal operation, the flap members 38 are disposed as shown at the lefthand side of Fig. 1 and no fuel is supplied to the injectors 35. For increased thrust however, the flaps 38 are moved to the position shown at the right-hand side of Fig. 1 and fuel is now supplied to the injectors 35 so that the jet stream from the engine comprises an inner stream of turbine exhaust gases, an intermediate stream of combustion gases from the inner duct 32 and an outer stream of air from the outer duct 33. The downstream end of the partition may be corrugated; or it may be axially movable so as to vary the cross-sectional area of the nozzle.
