| Abstract: | We have studied the possibility of using the method of double-position optical sounding for observation of inhomogeneities
in an absorption index of a turbid medium at very large optical depths where the light field becomes isotropic. Formulas for
calculating the image inhomogeneity, its contrast, signal-to-noise ratio, sighting distance, and an optimal “radiator-receiver”
base have been obtained. We propose a system of double-position sounding with a rotary base, which allows us to improve the
probability of detecting an inhomogeneity and finding its location with a higher accuracy. We show that the method of continuous
optical sounding can be used for observation of inhomogeneities in living tissues at depths of several tens of transport paths.
