摘要

本文基于扩展的惠更斯-菲涅耳积分，导出了描述扭曲高斯-谢尔模型阵列（TGSMA）光束通过湍流生物组织传播特性的解析表达式。利用这些公式，详细研究了TGSMA光束在湍流生物组织中的旋转和融合特性。研究发现，TGSMA光束除了在近场发生断裂和旋转现象外，在远场还经历了明显的融合期，湍流生物组织在TGSMA光束的融合中起着主导作用。这些新的结果可能有助于光学捕获。

Properties of the Rotation and Mergence of Twisted Gaussian Schell Model Array Beams Propagating in Turbulent Biological Tissues

In this paper, an analytical expression for describing propagation properties of twisted Gaussian Schell model array (TGSMA) beams through turbulent biological tissues is derived based on the extended Huygens Fresnel integral. With the help of the formulae, properties of the rotation and mergence for the TGSMA beams in turbulent biological tissues are researched in detail. It is found that the TGSMA beams go through the distinct mergence period in the far field besides phenomena of abruption and rotation in the near field, and turbulent biological tissues play a dominated role in mergence of the TGSMA beams. These novel results may be helpful in optical trapping.
