Woofer-tweeter adaptive optics in very strong turbulence using a magnetic-liquid deformable mirror

摘要

We present progress towards the development of a woofer-tweeter adaptive optics (AO) system using the first 37actuators of a 91-actuator magnetic-liquid deformable mirror (MLDM) and a magnetic 97-actuator DM from ALPAO.The MLDM, which has both very large single-actuator and inter-actuator strokes, but a low bandwidth, is used aswoofer, whereas the high bandwidth and lower stroke ALPAO DM is used as tweeter. The ALPAO DM should improvethe bandwidth of the MLDM while the MLDM will allow correction of strong aberrations.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
