What is it about?

In this work the rainbow schlieren technique is applied for visualizing the ultrasonic field and adjusting a standard single-axis levitator known as TinyLev.

Why is it important?

To optimize the performance of acoustic levitators based on multiple inexpensive transducers, the correct alignment of their components is crucial.


Optimizing the levitators constructed with inexpensive transducers have practical consequences such as the improved levitation capability that allows to levitate and manipulate a wide range of materials, previously only available to levitate with Langevin-based levitators and other levitation technologies.
