This paper discusses and studies the composition and characteristics of biospeckle on the surface of bone tissues. We used a laser speckle device to capture biospeckle patterns from fresh pig bone tissue. Traditional speckle activity metrics were used to measure the speckle activity of ex vivo bone tissue over time. Both Gaussian and Lorentzian correlation functions were used to characterize the ordered and disordered motion of the bone surface, together with volume scattering, to construct the model. Using the established mathematical model of the spatio-temporal evolution of the biospeckle pattern, it is possible to account for the presence of volume scattering from the biospeckle of bones, quantify the ordered or disordered motions in the biological speckle activity at the current time, and assess the ability of laser speckle correlation technique to determine biological activity.

生物散斑激光系统下评价骨组织散斑活性和特征的数值模型

本文讨论和研究了骨组织表面生物斑的组成和特征。我们使用激光散斑装置从新鲜猪骨组织中捕获生物散斑图案。传统的散斑活性指标被用来测量散斑活性离体骨组织随着时间的推移。高斯和洛伦兹相关函数都用于表征骨表面的有序和无序运动，以及体积散射，以构建模型。使用已建立的生物散斑模式时空演化的数学模型，可以解释骨骼生物散斑的体积散射的存在，量化当前生物散斑活动中的有序或无序运动，以及评估激光散斑相关技术确定生物活性的能力。
