The system demonstrated the capability to reach 0.33-arcsec resolution in visible wavelengths.

High resolution was maintained across a field of view up to 30 arcsec in diameter under challenging seeing conditions (1-3 arcsec).

Conclusions:

The 19-segment adaptive-mirror system effectively mitigates atmospheric turbulence.
This technology significantly enhances the resolution and image quality of ground-based telescopes.
The system shows promise for improving visible light astronomical observations.
