CONTACTLESS DEVICE FOR DETERMINING BIOLOGICAL AGENTS AND CHEMICAL SUBSTANCES IN BIOLOGICAL MEDIA

摘要

The invention relates to medical and veterinary diagnostic engineering and can be used for a non-invasive express-detection of any biological agent (virus or bacterium) or a chemical substance, for example drug or alcohol in a human or animal organism. Said invention makes it possible to ensure analysis continuity, small size and high operation speed of a device and to extend the functional capabilities thereof. Said invention enables to contactlessly control an object, what is very essential for controlling highly dangerous viruses and bacteria. The inventive device for detecting microorganisms and organic substances comprises laser radiation sources (from one to three), a device for exciting electromagnetic oscillations in the organism, a device for receiving and pre-processing the intensity of the radiation backscatter from the object, a spectroanalyser, an information storing device comprising a pre-recorded data base of the spectra of the definable agents and chemical substances, a micro-program control device, an optoelectronic device for filtering, comparing and recognising signals, a system for signal mathematical processing, liquid crystal display or a computer.
