Abstract

We have built and tested a 30 cm x 5 cm aperture telescope which uses six moveable mirrors to compensate for atmospherically induced phase distortion. A feedback system adjusts the mirrors in real time to maximize the intensity of light passing through a narrow slit in the image plane. We have achieved essentially diffraction-limited performance when imaging both laser and white-light objects through 250 meters of turbulent atmosphere. The system has yet to achieve its full potential, but has already operated successfully for objects as dim as 5th magnitude. It is presently installed on an equatorial mount at an observatory, and we hope by the time of the conference to present preliminary results with astronomical objects.
