Intensity correlations in turbulent biological tissues are evaluated when collimated Gaussian laser beam is used. Variations of the intensity correlations in biological tissues are investigated versus the diagonal distance from the origin of the observation plane for various tissue distances, biological tissue types, strength coefficients of the refractive-index fluctuations, starting points at the observation plane. Also, intensity correlations in biological tissues for various biological tissue types versus the strength coefficient of the refractive-index fluctuations, small length-scale factor, fractal dimension. It is found that intensity correlations become smaller at larger diagonal distance, tissue distance, strength coefficients of the refractive-index fluctuations, and at smaller source size, small length-scale factor and fractal dimensions. Behaviour of the intensity correlations is found to depend on the type of the biological tissue. Our results can be used in tissue identification and to find the disorders in biological tissues.

当使用准直的高斯激光束时，会评估湍流生物组织中的强度相关性。对于各种组织距离，生物组织类型，折射率波动的强度系数，观察平面的起点，研究了生物组织中强度相关性的变化与距观察平面起点的对角线距离的关系。同样，对于各种生物组织类型，生物组织中的强度相关性与折射率波动的强度系数，小的长度比例因子，分形维数有关。发现在更大的对角线距离，组织距离，折射率波动的强度系数以及较小的光源尺寸下，强度相关会变小，小的长度比例因子和分形维数。发现强度相关性的行为取决于生物组织的类型。我们的结果可用于组织鉴定和发现生物组织疾病。
