Abstract

Measurements are presented of lens-atmosphere modulation transfer functions for short-exposure speckle imaging at the AMOS observatory in Maui, Hawaii. Star images were recorded with a video sensor system and processed digitally. Near-diffraction-limited modulation transfer functions were recorded and analyzed for a 122 cm aperture instrument during fair to poor seeing conditions. Mean values for r0, the aperture wavefront correlation scale, ranged between 4.1 and 6.4 cm. Total projected rms image wander ranged from 0.2 to 1.1 arcsec. The results are in substantial agreement with theoretical predictions and laboratory simulation results.
