Robo-AO is the first autonomous laser adaptive optics system and science instrument operating on sky. The system robotically executes large scale surveys, monitors long-term astrophysical dynamics and characterizes newly discovered transients, all at the visible diffraction limit.
This video shows the propagation of the UV laser used for measuring atmospheric turbulence for each target observed. For more on how the system works, please see:
