Abstract

Branch points form from interference within a propagating wave due to phase differences imparted by atmospheric turbulence. In the companion paper, we demonstrated that the characteristics of density and separation found in our experimental work are reproducible in an independent wave optical simulation. In this paper, we expand on this demonstration to include the measurement of the number and velocities of branch point producing turbulence layers as well as the existence of persistent pairs in pupil plane measurements. Together these two papers verify our previous experimental results on pupil plane branch point measurements.
