Abstract
Modern photonics methods are considered in relation to solving a number of diagnostic problems in practical medicine. The basic principles of the application of optical noninvasive diagnostic methods are described and examples are given: laser Doppler flowmetry, digital diaphanoscopy, Raman spectroscopy, spectrophotometry, time-resolved fluorescence spectroscopy, and video capillaroscopy. The advantages and prospects of using photonics methods in clinical practice, making it possible to detect various pathological conditions of biological tissues, including those at the early stages of diseases, are demonstrated.
