A novel technique for biological kinematic analysis is proposed that makes use of the pseudophase singularities in a complex signal generated from a speckle-like pattern. In addition to the information about the locations and the anisotropic core structures of the pseudophase singularities, we also detect the spatial structures of a cluster of phase singularities, which serves as a unique constellation characterizing the mutual position relation between the individual pseudophase singularities. Experimental results of in vivo measurements for a swimming fish along with its kinematic analysis are presented, which demonstrate the validity of the proposed technique.
提出了一种用于生物运动学分析的新技术，该技术利用从类散斑图案生成的复信号中的伪相奇点。除了关于伪相奇点的位置和各向异性核心结构的信息外，我们还检测了相奇点簇的空间结构，它作为一种独特的星座表征了各个伪相奇点之间的相互位置关系。给出了对一条游动鱼的体内测量实验结果及其运动学分析，证明了所提技术的有效性。
