Description
A procedure has been developed to compute static aberrations once the
telescope PSF has been measured with the lucky imaging technique, using
a nearby star close to the object of interest as the point source to
probe the optical system. This PSF is iteratively turned into a phase
map at the pupil using the Gerchberg-Saxton algorithm and then converted
to the appropriate actuation information for a deformable mirror having
low actuator number but large stroke capability. The main advantage of
this procedure is related with the capability of correcting static
aberration at the specific pointing direction and without the need of a
wavefront sensor.
