A1 - Kotliar, Konstantin T1 - False spectra formation in the differential two-channel scheme of the laser Doppler flowmeter T2 - Biomedizinische Technik N2 - Noise in the differential two-channel scheme of a classic laser Doppler flowmetry (LDF) instrument was studied. Formation of false spectral components in the output signal due to beating of electrical signals in the differential amplifier was found out. The improved block-diagram of the flowmeter was developed allowing to reduce the noise.
