Partially coherent dual nonparaxial accelerating beams are constructed from the perspective of a superposition of fully coherent modes and incoherent interference effects among these modes. It is found that divergence angle and partial coherence of such beams can be altered by a curvature parameter. At the beginning of the propagation, such beams focus in the case of constructive interference, but they leave a central dip in the destructive case. Additionally, the extension of a crossed‐shaped intensity distribution caused by interference is slower than that of the transverse beam frame evidently. In particular, moving along the nonparaxial accelerating trajectory on the micrometer scale, the main lobes of these beams can diverge to a nearly flat angle. As such, these beams are likely to have applications in microscopic particle manipulation and coherence image processing.

部分相干双非傍轴加速光束
从完全相干模的叠加以及这些模之间的非相干干涉效应的角度出发，构造了部分相干双非傍轴加速光束。已经发现，这种光束的发散角和部分相干性可以通过曲率参数来改变。在传播开始时，此类光束在相长干涉的情况下会聚，但在相消干涉的情况下会留下中心倾角。此外，由干涉引起的十字形强度分布的扩展明显比横梁框架的扩展慢。特别地，沿着微米尺度上的非近轴加速轨迹移动，这些光束的主瓣可以发散到几乎平坦的角度。因此，
