Abstract

Flow measurements inside oscillating droplets are crucial for revealing potentials to save energy. However, aberrations of the light at the surface of the droplets results. In this paper, a novel measurement system is presented for both 3D imaging with only one camera and aberration correction. 3D imaging is achieved by introducing a Double-Helix Point Spread Function. The dynamically introduced aberrations of the phase boundary are measured with a Fresnel Guide Star and are corrected with a deformable mirror in a closed-loop system with low latency.
