TOWARD HIGH-RESOLUTION IMAGING WITH A SIMPLE ADAPTIVE-OPTICS SYSTEM

High-resolution imaging with reference to a widely separated star is e xamined. Peak tracking of the specklegram in the reference channel res ults in a high-resolution image in the observational channel. A binary star with angular separation of 30.5 arcsec is examined in white ligh t, and the resultant image of the primary star obtained with reference to the secondary star is shown to have better resolution than the cen troid tracking image by a factor of 3.
