透气性的半空显示器，如使用雾或细水雾的显示器，受到我们塑造和控制气溶胶的能力的限制，并处理两个主要问题：(1)系统的大小和复杂性，以及(2)为保持显示质量而产生的层流。在这里，我们介绍了SonicSpray，这是一种使用超声波贝塞尔波束来创建可重新配置的空中显示器的技术。我们用低成本、现成的零件制造原型。我们探索了SonicSpray在创建和重定向雾的层流方面的潜力和局限性。我们演示了一个工作原型，它仅通过6x6超声换能器阵列就可以精确控制层流气溶胶。描述了构建该器件的实现步骤，验证了显示器的控制和投影算法，并对其性能进行了评估。最后，我们报告了我们在学习、娱乐和艺术方面的几个有用的应用程序。
Permeable, mid-air displays, such as those using fog or water mist are limited by our ability to shape and control the aerosol and deal with two major issues: (1) the size and complexity of the system, and (2) the creation of laminar flow, to retain display quality. Here we present SonicSpray, a technique using ultrasonic Bessel beams to create reconfigurable mid-air displays. We build a prototype from low-cost, off-the-shelf parts. We explore the potential and limitations of SonicSpray to create and redirect laminar flows of fog. We demonstrate a working prototype that precisely controls laminar aerosols through only 6x6 ultrasound transducers array. We describe the implementation steps to build the device, verify the control and projection algorithm for the display, and evaluate its performance. We finally report our exploration of several useful applications, in learning, entertainment and arts.
