It has been shown that the method of digital dynamic photography is an effective technique for quantitative and qualitative diagnosis of the microcirculatory state of mouth tissues. As a result of the signal processing, one can obtain information on microcirculation indices from the spectral distribution of low-frequency variations of the speckle structure. The investigated method of digital dynamic speckle photography can be used to elucidate the haemodynamic features in tissues of the oral cavity even at early stages of the disease and then at the examination and treatment stages. New possibilities of digital laser speckle technologies for tomographic investigations of the near-surface blood flow at various depths with the use of two-lens optical configurations are illustrated.
