Figure 1: Phase streak and projection angle.
From: Single-shot tomographic movies of evolving light-velocity objects
(a) Schematic of chirped probe pulse crossing path of evolving index object Δn at laboratory angle θ, producing phase streak at projection angle φ. At tob=0, the index object (red circle) overlaps with the right side of the probe profile and the probe keeps going until tob=Lob/vob when it overlaps with the left side of the probe, leaving a phase streak across the probe. (b) Plot of φ versus θ for three different probe velocities, as indicated in legend. The object propagates at vob=0.68c in all three cases.
