Time-gated imaging of ballistic photons from a femtosecond laser source revealing the structures inside the dense cores of liquid-rocket-engine injector sprays. The ballistic-imaging concept is depicted at upper left; the associated instrumentation is presented schematically at upper right. Bottom figure: the six images in the top row reveal the core structures discernible through ballistic imaging; the six images in the bottom row show the limited core-structure information available through conventional shadowgraphy.
