title = "New simple phenomenological model for laser doppler measurements of blood flow in tissue",
abstract = "Laser Doppler flowmetry (LDF) for measurements of tissue blood flow is well-known today. The basic theory of forming the registered optical signal in LDF is the model developed by R.Bonner and R. Nossal. However, claiming to be a detailed and comprehensive analysis of the interaction of light with tissues, it does not describe many phenomena. Multiple simplifications and assumptions in the model diminish the efforts on the analysis of peculiarities of light scattering inside the tissue, resulting in a very approximate output. In this our study, a qualitatively similar result was obtained with the use of more simple and general approach. It was shown, that the power spectra of analyzed signals in the form of the exponential decay, similar to a fractal noise (1/f noise), is a consequence mainly of the Maxwell{\textquoteright}s distribution of moving particles{\textquoteright} velocities. Moreover, in contrast to the classic model, our model shows that the first moment of the frequency is linearly proportional not only to the velocity of red blood cells, but also is inversely proportional to the wavelength of illuminating radiation, that is more physically grounded.",
