Reference design of deformable mirror electronics for ELT systems

摘要

One of the first ELT AO systems to be deployed will be NFIRAOS of the Thirty Meter Telescope (TMT). NFIRAOS iscurrently being designed at the National Research Council of Canada's Herzberg Institute of Astrophysics (HIA).NFIRAOS incorporates deformable mirrors with much larger number of actuators than in current AO systems. To aidthe procurement of electronics for NFIRAOS DMs, a reference design is under way at the HIA. We have designed theoverall architecture, defined a command communication interface and developed a compact and cost-efficient highvoltage amplifier suitable for duplicating in 7673 copies for driving the two NFIRAOS DMs.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
