Abstract

An objective of our adaptive optics research at the 7-m Multiple Mirror Telescope (MMT) is to investigate ways of reconstructing wavefront errors accurately over large spatial scales. Correction of tilt error across and piston errors between each of the six 1.8-m diameter segments of the MMT is sufficient to recover the full diffraction-limited resolution at 2.2 μm of 0.06 arcseconds full width at half maximum1.
