It's not an easy thing for us, especially if vorticity is present, virtually impossible to visualize outside of a laboratory.
I think that may be the green flashing light in sequential serial like lines over form as seen in several still photos and videos posted over the years.

If so, I have no memory of it capturing vortex presence.

Frustrating that smoke in wind tunnel testing does little to illuminate vortex presence.
