High resolution imaging with reference to a widely separated star
Abstract
It is shown that high resolution imaging is possible by use of a reference star that is separated wider than the isoplanatic angle from the object under observation. A shift-and-add operation to the reference star results in a high resolution image of the object, though not diffraction-limited. Observational results on a binary star with angular separation of 22 arcsec indicate that a simple adaptive optics system is feasible in the visible region.
