Digital Laser Doppler Flowmetry: Device, Signal Processing Technique, and Clinical Testing

  • Published:
Biomedical Engineering Aims and scope

A method and a device for digital laser Doppler flowmetry are proposed. An approach to signal processing based on analysis of the power spectrum amplitude distribution over Doppler broadening frequencies is suggested. A prototype of the device is presented; its technical characteristics and settings used in tests are described. The method was tested in healthy volunteers of different ages and patients with type 2 diabetes mellitus. The research led to the development of binary classifiers for classifying volunteers and patients into groups according to the functional state of microcirculation.
