By applying quadratic and linear phase modulations (QPM and LPM), the propagation properties of the partially coherent dual and quad Airy beams which maintain acceleration in free space are studied. They are generated by superimposing two and four partially coherent Airy beams whose phase is modulated in the source field. It is demonstrated that the trajectories of the partially coherent light beams and the location and number of focal points, along with maximum altitude and range of the trajectories can be easily dominated by adjusting the appropriate values of QPM p and LPM l. Furthermore, for the quad case, the transverse spectral density distribution of lacking side lobes exhibits the structure of the optical frame which may be flipped under certain conditions. Both the peak intensity of the beams and the divergence speed of the optical frame can be managed by choosing the different characteristic transverse width of the beams. These results show an energizing new idea in the manipulation of partially coherent multiple fields of accelerating beams.

通过二次和线性相位优化部分相干多艾里光束的弹道运动

通过应用二次和线性相位调制（QPM 和 LPM），研究了在自由空间中保持加速度的部分相干双和四艾里光束的传播特性。它们是通过叠加两个和四个部分相干艾里光束而产生的，这些光束的相位在源场中被调制。结果表明，通过调整 QPM p和 LPM l的适当值可以很容易地控制部分相干光束的轨迹和焦点的位置和数量，以及轨迹的最大高度和范围. 此外，对于四边形情况，缺少旁瓣的横向光谱密度分布表现出在某些条件下可以翻转的光学框架的结构。光束的峰值强度和光学框架的发散速度都可以通过选择不同的光束特征横向宽度来管理。这些结果显示了在加速光束的部分相干多个场的操纵中的一个令人振奋的新想法。
