Paper Abstract

The adaptive optics techniques currently under development for telescopic mirrors of 8-m aperture class are presently projected to serve as the bases for mirrors of the order of 32-m diameter, in virtue of the rapid increase in the sensitivity advantage of diffraction-limited imaging with increasing aperture size. If the technology of atmospheric wavefront error sensing by means of artificial starlight is perfected, diffraction-limited imaging will be possible over the entire sky at even optical wavelengths. The corresponding resolution of 0.004 arcsec, in conjunction with the light-gathering power of a 32-m aperture, will constitute a milestone advancement for astronomical research prospects.
