  • 摘要: 本文研究了部分相干啁啾光学相干涡旋晶格在生物组织湍流中的平均光强和光谱位移,详细探讨了单色光场中的光学晶格结构和多色光场中的光谱快速跃迁特性。研究表明:在生物组织湍流中,光束从具有涡旋核的环形结构演变为具有暗区的周期阵列结构,最后呈类高斯图样。尽管晶格常数能调制光束结构,但它不影响光束在生物组织湍流中的光谱跃迁行为。光束在生物组织中的传输距离越小越有利于光谱快速跃迁,并且随着啁啾参数增大和脉冲持续时间的减小会导致发生光谱快速跃迁的横坐标减小。光谱跃迁和光谱位移会受到生物组织湍流的长距离累积效应的压制,并且湍流越强,其光谱位移越小。本文所得结果对生物组织中的图像识别、医疗器械和无损光学诊疗技术具有潜在应用。
