The Australian Astronomical Optics (AAO) consortium will design the new $AU32-million adaptive-optics system, called MAVIS, for the VLT in Chile.

An adaptive-optics system is made of three parts: a deformable mirror, which corrects the deformed light wave going through the atmosphere; a wavefront sensor, which senses the distortion of the light wave; and a real-time computer, which calculates the corrections.

MAVIS will have three deformable mirrors, eight wavefront sensors and five laser guide stars, and will use a technique called Multi-Conjugate Adaptive Optics to deliver its sharp images over a field of view 20 times larger than regular adaptive-optics systems.

mollwollfumble says that that is extremely impressive. I am always on the lookout for ways to increase the FOV but hadn’t thought of it in the context of adaptive optics.
