摘要：

A study was conducted to investigate the nature of biological zero in the dynamic light scattering diagnostic modalities. The standard diffusion-wave spectroscopy (DWS) system was used to measure the blood flow in the conditions of bio logical zero. The supply of low-intense laser radiation on the surface of the animal skin and the detection of the backscattered signal were performed by means of the optical-fiber contactless reflector-type transducer. The sensor part of the transducer contained a multi-mode fiber, which supplied the radiation, and a single-mode fiber in one cover. The detection of the backscattered laser radiation was performed in the photon counting mode using the avalanche photodiode (APD) whose output signal was analyzed using a digital self-corrector combined with a personal computer.
