Tunable acoustic gradient index of refraction lens

The tunable acoustic gradient index of refraction lens (or TAG lens) is an adaptive optics device filled with a fluid and driven by an acoustic wave. The very fast refractive index change induced results in a lens with tunable focal length at kHz rates, with applications in imaging and beam shaping.
