摘要
Two low-cost 3×3 and 4×4 segmented mirrors built for near-real time adaptive optics are described. The construction and performance characteristics of the mirrors are discussed and it is shown that they have the potential to provide very good correction of atmospheric aberration despite their low number of segments. Their use in an adaptive optics system is described.
