Paper Abstract

A number of experiments have been made with two adaptive optical systems. A 19 element deformable mirror with serial hilt-climbing control system is used to correct static wavefront errors. A system with 21-element deformable mirror and real-time wavefront sensing with shearing interferometer is used to correct dynamic errors. With this system two kinds of experiments have been made, in room correction of simulated disturbance and atmospheric compensation over a horizontal path of 340 meters. In these experiments reduction of the speckle pattern to the Airy diffraction disc is demonstrated.
