In the present study, we propose an alternative to these high-speed imaging techniques. The method is based on the recently introduced virtual frame technique, which relates the motion of a monotonic propagating front to the resulting image blur captured on a long-exposure shadowgraph. We use a consumer-level camera to photograph the entire collapse phase of cavitation bubbles. We then demonstrate that both the dynamics of a spherically collapsing bubble and those of a bubble collapsing near a rigid boundary can be accurately reconstructed from this single photograph at a virtual frame rate of up to 2 Mfps on a 24.2 Mpx sensor.Technologytext::journal::journal article::research article
