In this work, we present a new partially coherent adjustable anomalous vortex laser beam (PCAAVLB) and introduce it into turbulent biological tissue. The equation of such PCAAVLB in turbulent biological tissue is obtained. By numerical analysis, the evolution of the intensity of such PCAAVLB in turbulent biological tissue is analyzed. It is found that the PCAAVLB in biological tissue can lose its ring shape and become a Gaussian beam, and a PCAAVLB with smaller topological charge M or coherence length σ will evolve into a Gaussian profile faster. The PCAAVLB in turbulent biological tissue with a smaller small-length-scale factor l0 or larger fractal dimension D will evolve into a Gaussian profile faster and have a larger intensity as z increases. The results may have potential applications in sensing under biological tissue environments and laser imaging in biology.
在这项工作中，我们提出了一种新型的部分相干可调反常涡旋激光束（PCAAVLB），并将其引入到湍流生物组织中。得到了这种PCAAVLB在湍流生物组织中的方程。通过数值分析，研究了这种PCAAVLB在湍流生物组织中的强度演化。发现生物组织中的PCAAVLB会失去其环形形状并变成高斯光束，并且拓扑电荷M或相干长度σ较小的PCAAVLB会更快地演化为高斯分布。小长度尺度因子l0较小或分形维数D较大的湍流生物组织中的PCAAVLB会更快地演化为高斯分布，并且随着z的增加强度会更大。这些结果可能在生物组织环境下的传感和生物激光成像中具有潜在应用。
