A megahertz-rate digital holography system
2021
Given the need for a simple and fieldable diagnostic that can enable
the study of ultrahigh-speed phenomena in three dimensions, this work
presents experiments and simulations to optimize and demonstrate a digital
in-line holography system with an acquisition rate of 1 million frames per
second. The system is used to study the collision of a supersonic
projectile and its bow shock with 1 mm diameter water droplets. The
holograms acquired are three-dimensionally reconstructed and de-twinned to
analyze shock wave phenomena in these supersonic impact events and
demonstrate the potential of ultrahigh-speed digital holography as a
robust technique to probe complex shock wave dynamics and droplet
breakup.
