摘要：The invention relates to method for imaging measurement of a moving orflowing target and to an imaging measuring device for implementing the aforementionedmethod. Moreover, the invention relates to the use of information measured by means ofimaging measurement in the control and/or adjustment of a process. According to theinvention, electromagnetic radiation obtained from the moving or flowing target (T) isfocused 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 transmitelectromagnetic radiation in manners differing from each other. Said at least first andsecond 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 propertiesof the target (T) are determined spectroscopically by comparing and/or combiningspectrally resolved information, which is recorded when a pixel which corresponds to adetermined part of the target kto be measured and is focused on the screen (DA) of thematrix 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 kindof imaging non-spectroscopic measurement and/or visualization of the target.
