Paper Abstract

We demonstrate that acoustic field-induced forces (FIF) can detach, trap, and translate particles with no physical contact. This technology thereby shows potential for cleaning optical surfaces without introducing damage to the surface as well as allowing for scale-up to cover large areas where an atmosphere exists such as prior to launch. Experiments relying on acoustic fields created a force field landscape in the region between a transducer and the contaminated glass surface. That force field was then responsible for removing dust particles, trapping them, and translating them to a repository site. We have established proof-of-principle through experiments that removed both well-controlled particles with a narrow diameter distribution, as well as Arizona road dust, with a wide diameter distribution from a glass surface.
