title: Isoplanatic degradation of tilt correction and short-term imaging systems.
abstract: A MTF is derived that includes isoplanatic effects of tilt correction or short-term imaging systems. The MTF is used to predict degradation in Strehl ratio or resolution due to tilt decorrelation on offset paths for long horizontal paths through constant turbulence and for space-to-earth paths through a path-dependent structure constant C(2)(n).
