We report the generation of acoustic hook beams by a holographic lens. Compared with the conventional method, the intensity of the hook beam is greatly improved and the bending position is adjustable. We further rotate the hook beam into a two-dimensional axisymmetric structure with a cavity in the middle, forming a self-healing bottle beam. As an experiment, the generated bottle beam is used to trap and manipulate a polystyrene particle in the center of the bottle in water. The self-healing property of the bottle beam may have potential applications in biomedical application to manipulate cells or tissues behind obstacles.

用于粒子捕获的声学钩形光束透镜

我们报告了全息透镜产生的声学钩形梁。与常规方法相比，钩梁强度大大提高，弯曲位置可调。我们进一步将钩梁旋转成中间有空腔的二维轴对称结构，形成自愈瓶梁。作为实验，生成的瓶子光束用于捕获和操纵水中瓶子中心的聚苯乙烯粒子。瓶梁的自愈特性可能在生物医学应用中具有潜在的应用，以操纵障碍物后面的细胞或组织。
