Noncoherent fluctuation spectroscopy (NFS) is described as an optical method for measuring the tissue blood perfusion. This method is based on the registration of low-frequency fluctuations of a backscattered signal from a tissue in the frequency ran

Amplitude modulation of backscattered light caused by blood volume fluctuations was studied in Laser Doppler Flowmetry. It was shown that the amplitude-modulated signal significantly contributes to the power spectral density of photocurrent and calcu

Noise in the differential-channel setup of a laser Doppler flowmeter was studied. Formation of false spectral components in the output signal due to electrical signals beating was found out. The improved block-diagram of the flowmeter allowing to red

As applied to the problems of medical laser Doppler flowmetry and based on a modified Kubelka–Munk two-flow model, analytic expressions have been obtained for the radiation power backscattered by biological tissue, taking into account the variable

Vision impairment is one of the most typical characteristics of multiple sclerosis (MS). This pathology develops due to the lesions of optic nerves and optic tracts in the brain or eye movement dysfunction. Low contrast vision impairment is very freq
