Abstract

The method of the qualitative bioliquids testing of chemical agents on their crystallographic by way of transformation of analog information contained in a crystallographic image in the digital form with the help of the Fourier optics methods and to process by standard methods of mathematical statistics is discussed. Experimentally with the help of correlator of a Vander Lugt it is possible to translate analog information contained in an image of a crystallogram into digital form. That chosen by us is informational - important elements had a narow band of spatial frequencies therefore it was possible to achieve invariance to a turn. For reaching invariance to a scale it is necessary to include into the scheme of a correlator a binary filter which would realize transformation of a Mellin. With its help it is possible to receive additional information about sizes of informational - significant elements, that is of interest for testing of crystallograms.
