We propose a novel approach for fast acquisition of multispectral images. Key-element of the proposed approach is the computer-controlled light source. It consists of a set of the light-emitting diodes and generates any predefined basic spectrum with possibility of fast switching from one spectrum to another. The feasibility of the proposed system is experimentally demonstrated by a test of metameric samples, which were correctly distinguished. Moreover, the measured data are used for fast and accurate sample recognition without reconstruction of the original reflection spectrum.
