Abstract

The invention is based on a method and a device for identifying properties of moving objects such as articles, materials, layers, inter alia. The data representing the properties of the objects are determined and evaluated by means of a spectral spatially resolved quantitative and/or qualitative analysis in real time. According to the invention, a spatially resolved spectral image of the object region to be measured is generated. Said image, prior to its evaluation, is subjected optically to a spatially resolved spectral masking which permits only selected significant spatially resolved spectral values and/or spectral ranges to pass. Afterwards, said significant spatially resolved spectral values and/or spectral ranges are optically compressed to form a readable data image. By virtue of the combination of the optical masking with an optical data compression, significant spectral data having a plurality of spectral properties can be compressed flexibly to form a new spatially resolved spectral image and the latter can be imaged on a multi- or one-dimensional line. The evaluation of the spectral image of an object takes place very rapidly, such that a high number of parts per second can be identified.
