Why won't the phase conjugation technique work in reverse to build a
large earth based telescope that removes the effects of atmospheric
turbulence?  One would need a laser in the field of view (on a
satellite, say) to determine the distortion during the trip down through
the atmosphere, then apply the correction for that distortion to all
incoming light to produce an undistorted image.  If it works, it sounds
like it could make the Space Telescope obsolete.
