Figure 9
Pump–probe single-pulse imaging of an exploding water jet. From left to right the time delay is varied = −4 ns, −9 ns, −16 ns and −30 ns. Top to bottom illustrates the workflow of data processing. Starting with the raw hologram, the flat-field corrected hologram and the retrieved phases. The two scales on the colorbar of the reconstructions indicate retrieved phase in radians on the right and electron area density in 106 e− nm−2 on the left. The last row shows the reconstruction divided by the average phase. This highlights smaller structures present in individual images, which are otherwise hidden by large phase shifts. The red arrows in the −16 ns panel indicate shocks traveling along the jet in opposite directions. The scale bar indicates 20 µm. |
