IV SOLARNET MeetingLanzarote, January 16-20, 2017
SOLARNET WP70 investigates the effects of air turbulence on wavefront distortion and analyses techniques to reduce and correct the optical degradation in order to improve the performance of existing solar telescopes and to optimise the design of EST.
