Abstract
The classical single conjugate adaptive optics system of the new 4-meter Daniel K. Inouye Solar Telescope is going to be replaced by a multi-conjugate system for adaptive optics supported observations of the Sun in an enlarged field of view. The multi-conjugate correction will expand the high-order adaptive optics wavefront correction over a wider field of view up to 1 arcminute. The ground-layer-only correction will uniformly improve the seeing across a field of view larger than 2 arcminutes for observations that require lower resolution but very large fields. Thus, the ground-layer & multi-conjugate adaptive optics upgrade will add new potential to the wavefront correction system and thereby boost the scientific output of the telescope. In this conference, we layout the overall project, its subsystems and the current status.
