Paper Abstract

Based on the measured height distributional data of the turbulent structure constant (Cn2), this article analyses the effect of turbulent outer scale (Lo) on atmospheric transverse coherence length ro and isoplanatic angle ((theta) o). The calculation result shows that ro and (theta) o will obviously increase when limited Lo is considered. The ro and (theta) o are much large for telescope at 2.2 micrometers . The limit of (theta) o is likely to be several arcminutes and may possibly be even larger.
